A 150 × 190 lift-up divan is a common couple-and-storage solution. Matching the mattress size is only the first check; access, external footprint and finished height can still derail the purchase.
Choose one box or two modules from the access route and required stability. Then confirm external dimensions, inner depth, finished height, lid clearance, mattress compatibility and the live delivery service before comparing price.
One box or two modules
A single box removes a central join but may not turn through the building. Modules simplify access but must be linked, level and stable.
Ask for transport dimensions for every package and confirm who assembles and levels the system.
Protect usable room space
Draw 150 × 190, then add sides, front, handle and headboard. Open doors and drawers over the full outline and preserve the routes both sleepers use.
Choose between 190 and 200 cm length before buying the base; the mattress, furniture and bedding must agree.
Capacity raises the whole bed
A deeper box stores more but raises lid, mattress and sleeper. Add every layer and test sitting and standing.
Compare usable depth and reach, not only litres. Storage that requires emptying half the bed is not practical capacity.
Put delivery into the price
Use the delivery postcode to verify room delivery, assembly, packaging removal and removal of the old base.
Read returns for opened or assembled furniture and save the exact variant and order conditions.
