Ottoman Bed Assembly: Steps, Tips and Common Problems
How an ottoman storage bed goes together, from base frame and gas lifts to headboard and slats, plus safety checks and the mistakes that cost time.
An ottoman bed lifts at the base to reveal a large storage space under the mattress. It is a clever design but a heavier, more involved build than a standard frame. Knowing how it works helps you avoid the common pitfalls.
What makes ottoman beds different
The lifting mechanism
Most designs use gas struts or hydraulic arms that raise the base. These are under pressure and should be handled according to the instructions, never forced or cut. Some designs have a hinged side opening or an end lift, so check which type yours is.
The weight
The base, the mattress platform and the upholstered frame together are heavy. A second person is almost always necessary, especially for a king-size or larger.
The upholstery
Fabric or faux leather scratches and snags easily. Protect it with the packaging and avoid dragging.
Before you start
- Clear a space larger than the bed, ideally the room where it will stand.
- Check the parts and the mattress size compared with the platform dimensions.
- Keep the mattress away from the build area.
- Read how the gas lift is installed, since some are supplied in separate boxes.
Typical assembly order
- Lay out the frame. Build the base frame upside down or on its side, as instructed, on a soft surface.
- Attach the legs or feet. Fit these before turning the bed over, as they bear the load.
- Fit the side rails and cross supports. Hand-tighten and check the frame is square.
- Install the lift mechanism. Attach hinges and gas struts exactly as shown. Wrong placement affects how easily it opens.
- Fit the platform or slats. Align it and check the movement before tightening fully.
- Attach the headboard. Usually bolted to the frame; check the height and alignment.
- Test the lift. Raise and lower a few times to check it opens smoothly and holds in position.
- Add the mattress. Place it only after checking everything is secure.
Safety points
- Never place hands where a closing platform could trap fingers.
- Do not overload the storage space beyond what the manufacturer allows.
- Check gas struts are rated for the weight of the mattress; a heavy mattress can overload a light strut.
- Keep children and pets clear during operation.
- Follow the manufacturer's instructions for the lift.
Common problems
The lid will not stay up
This often means the strut is the wrong rating for the mattress weight or is fitted wrongly. Check the instructions and the strut markings.
Squeaking or sticking
Check that bolts are tight and that the platform is not rubbing on the frame. Slight adjustment of hinges often fixes it.
Frame is not square
Recheck diagonals before final tightening. A twisted frame causes the platform to bind.
Time and help
A competent assembler usually builds an ottoman bed in one to two hours; first-timers should allow longer. See how long flat-pack takes and the cost guide. If you would rather not lift and align heavy parts yourself, you can send a request via services.
Tips for a two-person build
- Check the frame size against the mattress and the room, including space to open the lid.
- Assemble the base on the floor where the bed will stay, because it is heavy once built.
- Fix the lifting mechanism according to the manual, taking care not to trap fingers.
- Lift the base onto its legs, or lay it on the floor if the design is legs-free.
- Fit the slats and mattress platform, then the headboard.
- Test the lift several times before loading the bed with bedding.
What to check afterwards
- The lid stays open at the angle the manual describes.
- Nothing snags the mattress or bedding as it lifts.
- The base sits flat and does not rock.
- Bolts at the headboard and rails are tight.
- There is enough floor space to open the bed fully.
Common mistakes
- Choosing a mattress that is too thick or too heavy for the mechanism.
- Overloading the storage space with very heavy items.
- Fitting the headboard before checking the lift works.
- Pushing the bed into a corner so the lid cannot open.
Moving an ottoman bed
Because the base is heavy, plan moves carefully and consider whether it can be taken apart. The guide to dismantling furniture for a house move explains how to label fixings and keep the structure sound. For awkward upstairs rooms, ask for help.
Checking the gas lifts and weight limits
Gas lifts are rated for a particular weight range. A heavier mattress or a full load of storage can mean the lid drifts down, so check the rating in the manual before choosing the mattress. If a lift feels weak after assembly, it may be fitted the wrong way round or on the wrong setting. Do not top the base up with items that exceed the stated storage limit.
Frequently asked questions
Can I assemble an ottoman bed alone?
It is difficult and not recommended. Lifting the base and fitting the platform are two-person tasks, and the gas lifts need care.
Do gas lifts wear out?
Over many years they can lose strength. Replacement struts are often available from the manufacturer; check the part numbers before ordering.
Can I put a thicker mattress on an ottoman bed?
Check the manufacturer's limits for depth and weight. Too heavy or thick a mattress can strain the lift and affect closing.
