Why should you choose this mattress?
This is a firm mattress that still has some give at the surface. The Reflex foam shapes around your body, so the feel is cushioned but sturdy. The 800 pocket springs each move independently, which means the mattress can respond to your body rather than sagging as one piece. Soft white fibres increase airflow to help dispel heat, so it should feel fresher. It suits most back sleepers who want a firm bed, although you'll want to check it feels right in the first few weeks of the trial.
Key features & layer details
Reflex foam
A layer of Reflex foam that shapes around your body. It gives a cushioned yet sturdy feel, so the firm surface isn't harsh.
Soft white fibres
Soft white fibres that increase airflow to help dispel heat. This means the mattress should feel fresher through the night.
Dense polyester fibres
Two layers of dense polyester fibres that enhance the firm feel. They also give the spring system extra support.
Pocket springs
A core of 800 pocket springs, each encased in its own fabric pocket. Each spring moves independently, so the mattress can respond to your body.

Best suited for?
Back sleepers
The firm rating and dense polyester fibre layers give a sturdy, supportive surface, while the Reflex foam keeps it cushioned enough to feel comfortable.
Warm sleepers
Soft white fibres increase airflow to help dispel heat, which means the mattress should feel fresher through the night.
Couples
Each of the 800 pocket springs moves independently, so the mattress can respond to each person's body rather than sagging as one piece.
If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It's rated firm, and the foam layer only softens the surface a little. Side sleepers and lighter sleepers may find it hard on the shoulders and hips. It's single-sided, so you can rotate it but not flip it.
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.
