Why should you choose this mattress?
A medium soft feel suits sleepers who like to sink into their mattress a little rather than lie on top of it. Side sleepers in particular tend to get on well with softer surfaces, because the extra give helps the shoulder and hip settle in and keeps the spine straighter. Yes, the price is high, but Sealy is an established name and softer premium models are harder to find than firm ones. If you've been waking with pressure-point aches on a firmer bed, a medium soft option like this is worth a look.
Key features & layer details
AlignSupport coil system
A two-stage coil design that is described as sensing your shape and responding with the level of support you need. For you, that means support that adapts to your body rather than a single fixed feel.
Geltex comfort layer
A gel-infused foam with an open cell structure that lets air circulate. It adds cushioning, and the airflow should help keep heat from building up as you sleep.
ComfortCore
A foam layer placed in the centre third of the mattress, where it targets the hips and lower back. This gives extra cushioning right where most of your weight sits.
Quilted Euro pillowtop
A quilted top layer that sits above the comfort layers. It adds a soft, plush surface to settle into, which fits the medium soft feel.

Best suited for?
Side sleepers
The medium soft firmness gives extra give, so the shoulder and hip can settle in and the spine stays straighter while you lie on your side.
Couples
Four UK sizes, including King and Super King, give two people room to spread out on a surface that gently cushions both of them.
Lighter sleepers
A medium soft feel lets you sink in a little rather than lie on top, which suits people who don't need much pushback.
If you sleep on your front, or you're a heavier sleeper who needs plenty of pushback, a medium soft mattress may let your hips dip too far and leave your lower back aching. Budget shoppers should also look elsewhere: this is a serious spend.
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.
