Why should you choose this mattress?
The Belvoir suits sleepers who want firm support without a hard sleeping surface. The pocket springs respond independently to your body, which means less motion transfer if you share a bed, while the memory foam and knitted pillowtop soften the feel where your shoulders and hips press in. Delivery is free on all orders, with a two man service to your room of choice, which matters with a 28cm deep mattress. The guarantee is short at one year, but the 100 Night Comfort Guarantee lets you exchange it if the firm tension turns out to be too much. If you sleep on your back or front and tend to sink into softer mattresses, this is worth a look.
Key features & layer details
Knitted pillowtop
A soft knitted pillowtop with a sumptuous pillow top finish, which adds extra depth. In practice this gives a cushioned first impression before you reach the firmer support below.
Memory foam
A layer of soothing memory foam that relieves pressure and works with the pocket springs beneath. It adapts to your movements during the night, so you get embracing support rather than a rigid feel.
Pocket springs
1,015 individually wrapped pocket springs in the king size. Each spring moves independently, which means support that follows your shape and less disturbance from a partner shifting about.

Best suited for?
Back sleepers
The firm tension and pocket springs give steady support under the hips and spine, while the pillowtop keeps the surface from feeling hard.
Front sleepers
Firm support from the pocket springs helps stop you sinking too deep, and the knitted pillowtop and memory foam keep the surface comfortable.
Couples
Each of the 1,015 individually wrapped pocket springs in the king size moves independently, so you feel less disturbance when your partner shifts about at night.
Heavier sleepers
A firm tension over pocket springs and memory foam gives support that resists sinking, which suits anyone who tends to dip into softer mattresses.
Allergy sufferers
The cover includes antimicrobial SmartSilver for better sleep hygiene, which gives a cleaner sleep surface for people who are particular about how fresh their bed stays.
This is a firm tension mattress, so lightweight side sleepers may find it too unyielding despite the pillowtop, with pressure building at the shoulder. The one-year guarantee is short, and the 100 Night Comfort Guarantee offers an exchange, not a refund, which won't suit anyone wanting a no-quibble money-back trial.
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.
