Why should you choose this mattress?
The springs are the main draw. Up to 1,800 individually pocketed springs (that figure is for a king) move independently, and a layer of mini pocket springs sits on top of them, so the support should feel responsive rather than stiff. Above that, traditional memory foam eases pressure points, while the Staycool gel memory foam is there to help manage moisture and temperature. It's a sensible pick for back sleepers and combination sleepers who like a medium-firm feel, and the 10-year Simmons guarantee adds reassurance. Lighter side sleepers may find it a little firm.
Key features & layer details
Soft knitted sleep surface
A soft, breathable knitted cover that adds a plush feel. It gives you a comfortable first touch without making the mattress feel soft overall.
Soft white fibres
A filling made from 100% polyester that offers good recovery and is very durable. It keeps the surface comfortable for longer.
Traditional memory foam
A memory foam layer that contours to your body to relieve pressure points. You get personalised cushioning, which helps at the shoulders and hips.
Staycool gel memory foam
A gel memory foam that gives cooling comfort and gentle pressure relief while helping manage moisture and regulate temperature. It's there to keep you feeling fresher through the night.
Mini pocket springs
A layer of mini pocket springs working alongside the main spring system. It makes the surface supportive and responsive, so you're not sinking too far into the foam.
Pocket springs
Up to 1,800 individually pocketed springs in a king size, each working independently. They give better pressure-relieving support and limit how much you feel a partner's movement.

Best suited for?
Back sleepers
A medium-firm feel with a layer of mini pocket springs on top keeps the surface supportive and responsive, so you aren't sinking too far into the foam.
Combination sleepers
Responsive mini pocket springs sit under the foam, which means the surface should feel easy to move across rather than stiff when you change position.
Couples
Up to 1,800 individually pocketed springs in a king size each work independently, which limits how much you feel a partner's movement during the night.
Warm sleepers
The Staycool gel memory foam helps manage moisture and regulate temperature, so you should feel fresher through the night, and the knitted cover is breathable.
If you prefer sleeping on a soft mattress, this might not be the best choice. It's rated medium firm, and the memory foam sits over a fairly supportive spring base. Lighter side sleepers who want a deep, sinking feel may find it too firm.
Save on an earlier or ex-display model
