Measuring for delivery
Make sure you check stairwells and doors before ordering a mattress so that you can ensure it will fit.
Rolled mattresses from Silentnight ease transport.
Depth and bedding fit
Average mattress depth is 25–30 cm; deeper luxury models up to 35 cm and will require the use of extra‑deep sheets.
Choosing frame size
Make sure you allow for at least 60 cm walking space each side; ottoman storage needs extra clearance.
