Assessed from Feather & Black's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
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 & what's inside
- 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.

Who's it NOT for?
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.

How firm is the Feather & Black Belvoir mattress?
Feather & Black describes it as a firm tension pillowtop mattress. The knitted pillowtop and memory foam soften the surface feel, but the underlying support is firm, so it suits back and front sleepers better than lightweight side sleepers.
How many springs does the Belvoir mattress have?
The king size contains 1,015 individually wrapped pocket springs. Feather & Black doesn't specify the spring count for other sizes, so smaller sizes may differ.
Does the Feather & Black Belvoir come with a trial?
Yes, Feather & Black offers a 100 Night Comfort Guarantee. Be aware this allows an exchange if you're not satisfied, rather than a refund, so read the terms carefully before ordering.
How is the Belvoir mattress delivered?
Delivery is free on all orders, with a two man service to your room of choice. Feather & Black anticipates delivery within 14 days after the mattress reaches the delivery depot.
How deep is the Feather & Black Belvoir mattress?
It's 28cm deep, which includes the pillowtop layer. Worth checking your fitted sheets are deep enough before it arrives.
