Why should you choose this mattress?
The Silk Pocket 1400 is a firm mattress, so it suits people who like a supportive, less sinking feel, such as back sleepers. Lighter side sleepers may find it a little unforgiving. Its pocket springs sit in cloth sleeves, so each spring works on its own. The fillings are natural, including silk, wool, cotton and cashmere, and the mattress is chemical treatment-free, which may appeal if you want to avoid treated materials. A wire edge border helps the sides hold their shape. It's single sided, so rotate it head to toe rather than flipping it, and the turning handles on the border make that easier. The depth is 27cm.

Best suited for?
Back sleepers
The firm feel gives a supportive, less sinking surface, which means your body stays on top of the mattress rather than settling deep into it.
Eco-conscious buyers
Natural fillings including silk, wool, cotton and cashmere, plus a chemical treatment-free build, suit anyone who wants to avoid treated materials in their bed.
Couples
Pocket springs in cloth sleeves let each spring work on its own, and the wire edge border helps the sides hold their shape for sharing.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.
