Comes From: The UK
Cost: £599 for a double, £699 for a king
Trial Period: 100 nights
Construction: "Simbatex" (latex) top layer, conical pocket spring layer, visco memory foam layer, and a seven-foam base layer (25cm total)
Simba ups the ante of these new-wave mattresses by including pocket springs alongside all the foam and latex, so if you're struggling with the idea of a mattress without springs, this could be the one for you. However, those springs come at a price: this is at the top end of the market. The designers describe the springs as "the missing ingredient," but the mattress still comes rolled in a box like other brands and contains three layers of foam alongside springs for optimal support. If you want to try before you buy, this mattress is sold in some John Lewis stores as well as online.
