Why should you choose this mattress?
The Silentnight Just Sleep Calm is a medium-firm hybrid, so it suits people who want a balance of cushioning and support rather than a very soft or very hard feel. The Vitalize fabric surface absorbs body heat, and the high-density ReVo foam is there for airflow, which should help if you tend to sleep warm. Mirapocket pocket springs give the support underneath, and edge-to-edge support means you can use more of the mattress surface. It is made in the UK and comes in a box, rolled up, which makes it easier to get up the stairs. Silentnight states a 20-year guarantee. The main downside is that a medium-firm feel may be too firm for lighter side sleepers who want a plush surface.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
Warm sleepers
The Vitalize fabric surface absorbs body heat and the high-density ReVo foam is there for airflow, which should help you stay more comfortable if you sleep warm.
Couples
Edge-to-edge support means you can use more of the mattress surface, so two people have more usable room before reaching the sides.
Back sleepers
A medium-firm feel with Mirapocket pocket springs underneath gives a balance of cushioning and support, rather than a very soft or very hard surface.
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.
