How to prepare for furniture assembly

How much room is needed for furniture assembly?

The finished footprint is only part of the space needed. Panels may need to be laid out, a frame may be built flat before being raised, and the fitter needs working room around it. Some products must be assembled upright or have a stated minimum ceiling height, so the exact instructions matter.

Share the product link and the intended location. A room photo, rough room dimensions and the ceiling height can identify obvious constraints. Check doors, drawers, radiators, sockets and skirting as well as the empty floor area. A wardrobe that fits the wall width can still obstruct a door or require space above it during assembly.

• Assembly space: enough clear floor for the largest panels and the build method in the instructions.
• Final space: width, depth and height including handles, feet, top trims and any required wall gap.
• Usable space: doors and drawers can open without hitting a bed, radiator or another unit.
• Delivery route: the largest package can reach the room through the available doors and turns.

Should I unpack the furniture before the visit?

Keep the packages together with their labels and assembly instructions. Check that the delivery contains the expected number of boxes and report visible damage or missing packages to the retailer. Unless another arrangement has been agreed, avoid mixing hardware from different items or removing labels that identify similar panels.

• Keep instructions, fittings and small parts with the correct item.
• Photograph damaged packaging or parts before disposing of the packaging.
• Tell us if boxes remain downstairs or in another building.
• Do not struggle with heavy packages simply to place them in the final room.

If a delivery is incomplete, tell us before the appointment. A missing structural panel is different from a minor cosmetic defect, and the supplier may need to resolve it before the assembly can be completed.

Does the furniture need securing to a wall?

Furniture needs wall securing when its instructions require it, even if it appears steady while empty. An anti-tip restraint helps stop a floor-standing unit overturning; a suspension rail supports wall-hung furniture. They do different jobs and are not interchangeable. The restraint, its connection to the furniture and its anchorage into the wall must all be suitable.

Keep the supplied restraint and instructions with the unit. A replacement should be compatible with that furniture, rather than attached to whichever thin back panel is easiest to reach. Manufacturer wall-anchoring guidance confirms that the furniture and wall material both govern the hardware. IKEA's general anchoring leaflet is one example; your own unit's manual remains the reference.

The wall-mounting preparation guide explains why a painted surface alone cannot identify a suitable fixing. Where attachment is required but cannot be completed, the furniture should not be treated as ready for normal use.

Can furniture be secured when a skirting board leaves a gap?

A skirting-board gap does not automatically prevent wall securing. It changes the distance between the furniture and its anchorage, which the approved restraint or mounting arrangement must accommodate. Pulling the top of a unit backwards until it meets the wall can distort the furniture; levelling the unit and restraining it are separate tasks.

Show the skirting, any gap and the supplied attachment arrangement in your enquiry. An even gap caused by a projecting skirting board is different from a cabinet that leans, rocks or has diagonal door gaps. The latter can also involve the floor, feet or assembled frame. Do not cut the furniture, improvise a spacer or substitute an adhesive restraint merely to avoid the gap. The useful outcome is a level, correctly assembled unit with its required securing completed.

If drilling permission is unresolved, settle that before booking. Where the specified restraint cannot be fitted, keeping the unit empty is not a substitute for completing the required securing. The wall construction section explains why identical painted walls may need different anchorage.

What should I clear before the fitter arrives?

Clear personal items and fragile belongings from the working area and the route into the room. Make space for doors and drawers to open at the final location. Keep children and pets away from loose parts and the work area during assembly.

Mention stairs, tight turns, lift restrictions, parking arrangements and existing furniture that affects access. Moving or dismantling large old items is a separate task to discuss, not an assumption within a new assembly. Let us know about packaging or old furniture that you want removed so the arrangements can be clarified.

What if the furniture is already built but uneven?

Describe whether the unit wobbles, the doors have uneven gaps or the drawers catch. An assembly problem, an uneven floor and damaged components can produce different faults. The whole unit may need checking before a door adjustment will hold.

Our common door problems article explains the difference between alignment and damaged support. Include photographs of the whole unit and accessible hardware when discussing furniture assembly or a repair.
