Can You Put Any Mattress on an Ottoman Bed?

Yes, in general — memory foam, pocket sprung and hybrid mattresses all work on an ottoman bed base, as long as two things match up.

1. Size compatibility

The mattress needs to match the frame's exact UK size (single, double, king, super king) — there's no flexibility here, so always check before ordering.

2. Weight compatibility with the struts

The gas struts are rated for a specific weight range. A mattress significantly heavier or lighter than that range can cause the base to feel hard to lift or refuse to stay closed. See our strut ratings guide.

Does mattress thickness matter?

Thickness itself doesn't usually affect the mechanism — it's weight, not depth, that determines strut compatibility. Very thick, dense hybrid mattresses tend to be heavier, so factor that in.

Fitting mattresses for specific brands

Popular brands like Simba, Emma and Tempur all fit standard UK sizes and work fine on ottoman bases — the same size and weight rules apply regardless of brand.
