Why should you choose this mattress?
If you own one or are weighing it against a similar foam mattress, the build is sensible. The knitted cover is described as breathable, and the temperature-regulating top layer is aimed at keeping the surface comfortable, which matters if you tend to feel warm in bed. The contouring foam beneath is designed to follow the shape of your body, so it should suit people who like a cushioned, hugging feel. The high-density zoned foam base suggests different areas are built to support different parts of your body. Hyde & Sleep doesn't publish a firmness rating, so the exact feel is hard to judge from the specification alone.

Best suited for?
Warm sleepers
A breathable knitted cover and a temperature-regulating top layer are aimed at keeping the surface comfortable, which suits anyone who tends to feel warm in bed.
Side sleepers
Body-contouring foam beneath the top layer is designed to follow your shape, which should give a cushioned, hugging feel around the shoulders and hips.
Combination sleepers
The zoned foam base is built so different areas support different parts of the body, which should help as you change position through the night.
If you prefer the bouncy, airy feel of a sprung mattress, an all-foam build like this might not be the best choice. Hyde & Sleep doesn't publish a firmness rating or depth, so anyone who needs a particular feel or has a tall bed frame can't check those details beforehand. It also isn't currently on sale.
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.

FAQ's
Can you still buy the Hyde & Sleep Graphite?
It isn't currently on sale with the UK retailers we compare. The details here are mainly useful if you already own one or are comparing it with a similar mattress.
How firm is the Hyde & Sleep Graphite?
Hyde & Sleep doesn't publish a firmness rating for this mattress, so we can't give you a firm answer. The contouring foam layer suggests a cushioned feel, but that is an indication rather than a rating.
What sizes did the Hyde & Sleep Graphite come in?
It came in UK Single, UK Double and UK King. There's no listing here for other sizes, so if you need a Small Double or Super King, you'd need to compare a different mattress.
What is the Hyde & Sleep Graphite made of?
It's all foam. From the top, there's a soft-touch knitted cover, a temperature-regulating Kaygel top layer, a body-contouring foam layer and a high-density zoned foam base.
How deep is the Hyde & Sleep Graphite?
Hyde & Sleep doesn't publish a depth for this mattress. If you're checking it against a bed frame or fitted sheets, measure the mattress you own rather than relying on a listing.
