Cut-out shape

0 cm, give or take a centimetre. Measure from your slats to the top of the side rail: a mattress much deeper than the surround loses the edge support the frame was giving it.

Shallow enough for bunk beds, cabin beds and frames with a low surround, where a safety rail has to stand clear of the sleeping surface.

Yes, provided the slats are no more than 7 cm apart. Wider gaps let the mattress settle into them over time, and that is excluded from the guarantee. On a solid platform, stand the mattress on its side for an hour a few times a year so the underside can dry out.

No — it is a no-turn build. Rotate it head to foot every three months for the first year, then twice a year after that.

24 to 72 hours with a window open. It is the foam off-gassing and it is harmless. It is strongest on a rolled mattress in the first hour after unwrapping.

Free, tracked, one-person parcel delivery on rolled sizes. Deeper and hand-tufted builds ship flat on a two-person service and we book a slot with you.

Yes — add old mattress removal to the order and the driver collects it on delivery. It goes to a licensed recycler, not to landfill.
