Measure before choosing a model
Check the building entrance, staircase, lift and apartment door. Compare these measurements with the sealed package as well as the finished sofa. Record landing depth, handrails and turning space; a carton that fits a straight stair section may not turn on the landing.
Compare flexible formats
Single-seat, modular and folding formats may offer useful options for difficult access because some layouts can be handled in smaller parts. Confirm the actual number, dimensions and weight of packages rather than assuming every modular sofa arrives separately. Agree who will handle stairs before delivery day.
Allow recovery after opening
Keep the package sealed until it reaches the intended room. After opening, follow the model's instructions; current BoxSofa catalogue entries specify 24–72 hours for recovery. Leave room for expansion and avoid excessive weight in the first hours. Contact support if concerns remain after the stated window.
A practical checklist before you decide
- Check landing depth as well as stair width: the carton needs room to turn.
- Confirm package weight and appropriate help with the carrier; do not plan to carry it alone by default.
- Agree building access and any upstairs service before delivery day.
- Keep the sealed package intact until it reaches the intended room, following the handling instructions.
