Measure its actual transport shape
Measure the sofa at its largest fixed points, including arms, back and feet. Loose cushions reduce the transport dimensions only if they are removed. Check the manufacturer's information to see whether feet, side sections or modules are designed to come off. A part that looks separate is not necessarily intended for dismantling. Record the dimensions of each permitted transport configuration separately.
Note which surfaces are delicate and where the sofa can actually be held securely. Thin underside fabric, decorative arm panels and loose cushions are not dependable lifting points. The space needed by the people carrying it matters alongside the dimensions of the furniture itself.
Divide the route into stages
Start at the room exit and work towards the vehicle. Measure the usable doorway with the door fully open, rather than measuring just the frame. Look for handles, radiators, ceiling lights and handrails. Landings and changes of direction are especially important on stairs. Repeat the process in the new home; a generous building entrance says little about the final corridor.
A scale drawing helps you understand the layout, but it does not prove that a complicated turning movement will work. Protective blankets also add a little bulk. Avoid a plan that already depends on pressing the sofa against a wall or frame to make it fit on paper.
Decide before anyone lifts
Remove light obstacles and hold doors open appropriately. Removing building components or doors is not an automatic last-minute solution: responsibility, weight and fittings need checking first. Ask experienced furniture movers to assess narrow staircases, particularly heavy sofas or uncertain turns.
Agree where you can stop and put the sofa down safely before lifting. If it catches somewhere, do not push, pull and rotate simultaneously. Lower it in a controlled way and reassess. A moving blanket protects surfaces but cannot create missing room to manoeuvre.
