oSIST prEN 1129:2026 is a SIST draft standard for furniture foldaway beds. It specifies safety requirements and test methods for foldaway beds for domestic and non-domestic use, with the requirements limited to the foldaway function. It is written for manufacturers, test laboratories, installers, quality managers, and buyers who need to check safety, stability, mounting, operating forces, and product information.
What does oSIST prEN 1129:2026 specify?
oSIST prEN 1129:2026 covers safety requirements and test methods for foldaway beds, and only for the foldaway function. It applies regardless of materials, design, construction, or manufacturing process, but it leaves the rest of the bed and other product functions to other European standards.
The scope excludes safety that depends on the building structure, electrical safety, resistance to ageing, degradation, and flammability. It also excludes folding beds, camping beds, and convertible bed/chairs or settees that are covered elsewhere.
The document is organized into Clauses 1 to 11, followed by two informative annexes.
| Annex | What it covers |
|---|---|
| Annex A | Rationale for the requirements and tests |
| Annex B | Explanation of how to determine the number of fixings required per anchor device |
What are the key requirements of oSIST prEN 1129:2026?
oSIST prEN 1129:2026 is built around a set of practical checks for safe movement, stability, mounting, durability, and product information. In practice, it tells a test lab how to prepare the bed, what loads to apply, what counts as unacceptable movement, and what must be stated in instructions, marking, and point-of-sale information.
Test conditions and equipment
Clauses 4 and 5 require the bed to be tested as delivered, assembled and configured according to the supplied instructions, and set up in the most adverse configuration unless stated otherwise. The standard fixes how forces are applied, how long they are held, the tolerances for force, speed, dimensions, and angles, and it defines the loading pad and test floor.
That matters because results must be comparable between products and test houses. If the bed cannot be tested exactly as described, the lab has to use the closest practical method and record the deviation in the test report.
General safety and pinch-point control
Clause 6.1 requires manufacturer-made assembly and pilot holes, tool-only dismantling, and safe edges and corners on parts accessible during opening and closing. It also requires attention to the minimum and maximum mattress weight recommended by the manufacturer during testing.
Clause 6.2 addresses shearing and compression points. If handles or handgrips are used, their clearances must stay within the stated safe distances; if there are no handles, the moving and fixed parts must not create pinch points in the defined user zone. This is a direct design control on the places where fingers can be trapped during operation.
Stability and mounting to the building
Clause 6.3 covers the stability of free-standing foldaway beds in forward and rearward directions. The bed must not overturn in the forward stability test, and for the rearward test it must not tip beyond the stated angle, while the start-of-tilt force must exceed the stated minimum. The method uses the recommended heaviest and lightest mattresses, and the test is repeated for beds with multiple sleeping surfaces.
Clause 6.4 applies to beds fixed to a building structure. The bed needs at least two anchor devices, at least two holes in each, spacing between mounting holes greater than 50 mm, and fixings that cannot be released without a tool. The document also sets a minimum restraining force per anchor device and requires that value to be permanently attached to the rear of the bed and included in the installation instructions.
This matters because wall attachment is part of the safety case. The standard links the product marking, the instructions, and the mounting design so the installer knows what the wall and fixings must carry.
Opening, closing, unintended movement, and durability
Clauses 6.5 and 6.6 define how hard the bed may be to open and close. The opening force is limited, with two alternative opening behaviors allowed depending on whether the bed has an equilibrium zone, and the closing force must stay below the stated limit throughout the movement. The same clauses also set requirements for automatic movement after release of a lock and for how far the bed may move unintentionally.
Clause 6.7 checks durability. Non-electrically operated foldaway mechanisms are cycled 10,000 times, and electrically operated mechanisms are also cycled 10,000 times with a defined duty cycle. After these tests, the bed must still open and close as intended and still meet the opening and closing force requirements where applicable.
Clause 6.8 checks unintended closing, and Clause 6.9 checks unintended opening, including special cases for beds with a seat function or an additional table function. Clause 6.10 sets requirements for locking mechanisms, including residual force, two-action designs, or the need to raise the bed base, and it adds a 1,000-cycle durability test. For a buyer or engineer, these clauses are the core safety checks against accidental movement during use.
Test sequence, instructions, marking, and reporting
Clause 7 fixes the order of tests, which matters because some checks are repeated before and after durability testing. Clauses 8 to 11 then control what the user receives: installation instructions, permanent product marking, point-of-sale information, and the minimum contents of the test report.
That means the standard is not only about the product body. It also controls how the bed is identified, installed, and described to the user, which is important when the product is assembled on site or sold through retail channels.
What terms does oSIST prEN 1129:2026 define?
- Foldaway bed - a bed with an opening/closing mechanism that rotates about at least one horizontal axis so it can be stored against a wall or in a cabinet.
- Open position - the sleeping position of the bed.
- Closed position - the stored position of the bed.
- Parts accessible during opening and closing - parts that can be reached only while the bed is being opened or closed, with the recommended minimum mattress in place.
- Resisting force - the force needed to start the foldaway movement, whether opening or closing.
- Equilibrium zone - the angle range where the bed is in a balanced state between open and closed.
- Anchor device - the component used to fix the bed structure to a building structure.
- Locking mechanism - the assembly of locking device(s) and operating device(s) that keeps the product in position.
Who uses oSIST prEN 1129:2026?
oSIST prEN 1129:2026 is used by furniture manufacturers, product designers, and compliance teams developing foldaway beds for domestic and non-domestic use. Test laboratories and certification bodies use it to run safety, stability, durability, and movement tests.
Installers and building contractors use it when the bed is fixed to a wall or other building structure. Buyers, retailers, and quality managers use it to check whether the product information, marking, and installation instructions are complete and suitable for procurement or sale.
What changed in oSIST prEN 1129:2026 from the previous edition?
oSIST prEN 1129:2026 will supersede EN 1129-1:1995 and EN 1129-2:1995. The draft standard states these main changes compared with those earlier editions:
- requirements and test methods are combined in one document;
- test methods are updated or modified so they support the requirements properly;
- requirements for free-standing foldaway beds are added;
- a durability test for electrically operated foldaway bed mechanisms is added;
- requirements for beds with extra functions such as seating and tables are added;
- the structure is revised and aligned with other furniture standards;
- the unintended closing and opening requirements are changed to reflect actual risks;
- locking mechanism requirements and durability are added;
- instructions for use are updated;
- point-of-sale information is added;
- the former test scheme from Annex A is brought into the main text;
- a new informative Annex A gives the rationale;
- a new informative Annex B explains how to determine the number of fixings required per anchor device.
Which standards are used with oSIST prEN 1129:2026?
- EN 1728:2012 - provides seating test methods for strength and durability, and Clause 6.9.2 uses its seat loading point definition when a foldaway bed includes a seat function.
What does the oSIST prEN 1129:2026 document contain?
The document contains the scope, normative references, terms and definitions, general test conditions, test equipment requirements, and the detailed safety requirements for foldaway beds. It also includes the fixed test sequence, installation instruction content, marking, purchase information, and the minimum test report content.
Clause 6 is the main technical body and includes stability tests, mounting requirements, opening and closing behavior, durability cycling, unintended movement tests, and locking mechanism checks. The document also includes figures for the loading pad and for the key test set-ups, plus a formula-based method for mounting force assessment.
Annex A gives the reasoning behind the requirements, which helps users understand why each test exists and what risk it addresses. Annex B gives examples and calculation guidance for anchor-device fixings, including how wall type and fixing choice affect installation practice.

4 General test conditions
4.1 Preliminary preparation
The bed shall be tested as delivered. The bed shall be assembled and/or configured according to the
instructions supplied. Unless otherwise stated, the most adverse configuration shall be used for each test.
If mounting or assembly instructions are not supplied, the mounting or assembly method shall be
recorded in the test report. Fittings shall be tightened before testing and shall not be retightened unless
specifically required in the manufacturer’s instructions. If the configuration needs to be changed in order
to produce worst-case conditions, this shall be recorded in the test report.
Levelling devices shall be set as near as possible to 5 mm from their fully open position, whilst ensuring
the unit is horizontal to the floor.
For free-standing beds fitted with castors, the castors shall be set to the most adverse position and, for
lockable castors, the castors shall be locked.
Unless otherwise specified by the manufacturer, the sample for test shall be stored in indoor ambient
conditions for at least 24 h immediately prior to testing.
The tests shall be carried out at indoor ambient conditions but if during a test the temperature is outside
the range 15 °C to 27 °C the maximum and/or minimum temperature shall be recorded in the test report.
If a test cannot be carried out as specified, e.g. because a loading pad cannot be used for the application
of a force due to the design of a product, the test shall be carried out as closely as possible to that specified.
Any modification to the test method shall be technically justified and recorded in the test report. Before
beginning the testing, visually inspect the bed thoroughly. Record any defects so that they are not
assumed to have been caused by the tests. Carry out measurements, if specified.
4.2 Application of forces
The test forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic
load is applied. Unless otherwise specified, each specified force shall be maintained for not less than 10 s
and not more than 15 s.
The test forces in durability tests shall be applied at a rate to ensure that excessive heating does not occur.
Unless otherwise specified, each test force shall be maintained for (2 ± 1) s.
The forces may be replaced by masses. The relationship 10 N = 1 kg shall be used.
The weight of the loading pad and any associated equipment shall be considered when applying the test
load.
4.3 Tolerances
Unless otherwise stated the following tolerances are applicable:
— forces: ± 5 % of the nominal force;
— velocities: ± 5 % of the nominal velocity;
— masses: ± 1 % of the nominal mass;
oSIST prEN 1129:2025
— dimensions:
— all dimensions less than 200 mm shall have a tolerance of ± 1 mm of the nominal dimension;
— all other dimensions shall have a tolerance of ± 0,5 % of the nominal dimension;
— angles: ± 2° of the nominal angle.
The accuracy for the positioning of loading pads shall be ± 5 mm.
NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected
when the above tolerances are met.
5 Test equipment
5.1 General
Unless otherwise stated, the tests may be applied by any suitable device, because results are dependent
only upon correctly applied forces and not on the apparatus.
The equipment shall not inhibit deformation of the bed, i.e. it shall move so that it can follow the
deformation of the bed during testing, so that the loads are always applied at the specified points and in
the specified directions.
5.2 Loading pad
Rigid disc 200 mm in diameter, the face of which has a convex spherical curvature of (300 ± 5) mm radius,
with a 12 mm edge radius (see Figure 1).
Dimensions in millimetres
Figure 1 — Loading pad
5.3 Floor surface
A rigid, horizontal and flat surface.
oSIST prEN 1129:2025
6 Safety requirements
6.1 General safety requirements
All assembly and pilot holes shall be made by the manufacturer.
It shall not be possible to dismantle the bed or its components without the use of a tool.
During operation of the foldaway function (i.e. moving the bed from the closed position to the open
position and back):
a) Edges and corners of parts accessible during opening and closing shall be rounded or chamfered and
free from burrs and sharp edges.
b) There shall be no open-ended tubes in parts accessible during opening and closing.
The maximum and minimum weight of the mattress recommended by the manufacturer shall be taken
into account during the test.
6.2 Shearing and compression points
If handles/handgrips are used to open/close the bed, they, shall have safety distances in any position of
movement of ≤ 8 mm or ≥ 18 mm, between the handles/handgrips and other components.
If there are no handles/handgrips there shall be no shearing and compression points that can
reach < 18 mm between rigid moving and/or rigid stationary parts when operating the bed. This applies
to a zone measured from 1 000 mm up to and including 1 600 mm, measured vertically from the floor
surface, and 60 mm from the edge’s users may use for closing the bed.
6.3 Stability of free-standing foldaway beds
6.3.1 Stability – Forward side
6.3.1.1 Requirements
This requirement does not apply to beds, and their associated components (e.g. wardrobes into which
the bed is mounted) that are intended to be fixed to the structure of the building.
When tested in accordance with 6.3.1.2 the product shall not overturn.
6.3.1.2 Test method
Place the product on the test floor (5.3).
Place the heaviest mattress recommended by the manufacturer on the sleeping surface or apply an evenly
distributed load to the sleeping surface such that the total load and centre of gravity is equivalent to the
maximum mattress weight and dimensions recommended by the manufacturer.
Castors shall be in the position most likely to cause overturning.
Open and close the bed 10 times.
Block the foldaway mechanism at a 70° angle in relation to vertical with a strap fixed from the upright
structure to the bed base structure, or by other suitable means, without preventing lifting and/or tipping
of the bed (see Figure 2).
Apply a force to the front edge of the movable part vertically with 750 N, (see Figure 2). Record if the
product overturns.
oSIST prEN 1129:2025
For beds with multiple sleeping surfaces in a structure that can be opened and closed separately, the tests
shall be carried out as follows:
— Open the beds.
— Position the heaviest mattresses in the beds.
— Block the foldaway mechanism of the lower bed at a 70° angle in relation to vertical with a strap fixed
from the upright structure to the bed base structure, or by other suitable means, without preventing
lifting and/or tipping of the bed. Simultaneous, apply on the lower bed, a force to the front edge of
the movable part vertically with 750 N and on the highest, a force of 750 N bed on a line located
inwards 200 mm from the outer side opposed to the axis of rotation of the bed (see Figure 3).
— Record if the product overturns.
Repeat the test with the lightest mattress recommended by the manufacturer on the sleeping surface, or
an evenly distributed load such that the total load and centre of gravity is equivalent to the minimum
mattress weight recommended by the manufacturer.
For safety during this test, the foldaway bed shall be secured so that it cannot tip more than 10° in relation
to vertical.
This test also verifies, in the event of a foldaway mechanism jamming, that the self-stabilizing function is
maintained.

the bed is mounted) that are intended to be fixed to the structure of the building.
When tested in accordance with 6.3.2.2 the product shall not tip over at an angle of greater than
15 degrees and at the start of tilt, the minimum force shall be greater than 150 N.
6.3.2.2 Test method
Place the product on the test floor (5.3), without a mattress on the sleeping surface.
The foldaway bed shall be in closed position.
Apply a horizontal force of maximum 500 N acting rearward, from the side where the bed is opened/
manoeuvred, acting 50 mm from the top edge of the foldaway bed or maximum 1 300 mm from the floor.
If the foldaway bed starts to tilt continue applying the force until it starts to tip over or until it has moved
15 degrees from the original position. Record the maximum tilting force applied and the reached angle of
movement.”.

6.4 Mounting of the bed to the building structure
6.4.1 Requirement
This requirement does not apply to beds that are intended to be free standing and to construction not
supported by the floor in the closed position and/or the sleeping surface in the open position is not
supported directly by the floor.
NOTE 1 If a construction is not supported by the floor in the closed position and/or the sleeping surface in the
open position is not supported directly by the floor, (additional) individual considerations for a safe mounting are
needed.
The bed shall be constructed such that its mountings comply with the following requirements:
a) there shall be at least two anchor devices, and;
b) there shall be at least two holes for attachment in each of the anchor devices, and;
c) the distance between the centre of any two mounting holes shall be greater than 50 mm, and;
d) the design of the anchor devices shall be such that no additional stress shall be transferred to the
anchor devices caused by the sagging of the floor by up to 10 mm maximum.
NOTE 2 Sagging of the floor can be caused by the use of carpets or rugs for example. An anchor device with a
vertical oblong hole allowing a minimum adjustment of 10 mm represents an acceptable solution if the instructions
for use are explicit on the assembly of the product in order to compensate for any sagging of the product after initial
assembly.

e) It shall not be possible to release the fixing devices without the use of tool.
f) The force F (see 6.4.2) shall be ≥ 400 N. For safety reasons, if the calculated F is < 400 N, consider
c c
F as 400 N. The information of the value shall be permanently attached on the rear side of the bed
c
and in the installation instruction to make clear what is the relevant tensile force acting at the level
and where the anchor devices are positioned.
NOTE 3 Explanation of the determination of the number of fixings required per anchor point/fixing device can
be found in Annex B.
6.4.2 Test method
Place the heaviest mattress recommended by the manufacturer on the sleeping surface, or apply an
evenly distributed load to the sleeping surface such that the total load and centre of gravity is equivalent
to the maximum mattress weight and dimensions recommended by
