Why should you choose this mattress?
The main draw is the soft, sink-in comfort, backed by Sealy's Posturepedic orthopaedic support system and AlignSupport coils underneath, so the cushioning has structure beneath it. INFUSE Black Diamond Graphite foam is there to keep the surface cooling, which should help if you tend to warm up in bed. The cover is breathable with anti-allergy protection, and reinforced edge support makes the sides steadier to sit on or sleep near. The Eco ComfortCore is plant based, a small plus if materials matter to you. It suits sleepers who like a plush feel, although those wanting a firmer surface may find it too soft.
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
INFUSE Black Diamond Graphite foam is there to keep the surface cooling, which should help if you tend to warm up in bed.
Allergy sufferers
The breathable cover has anti-allergy protection, which gives you a sleeping surface designed with allergy concerns in mind.
Eco-conscious buyers
Its Eco ComfortCore is plant based, so you get a small material benefit alongside the plush, sink-in comfort.
Couples
Reinforced edge support makes the sides steadier to sit on or sleep near, so there is more usable space across the bed.
Side sleepers
The soft, cosy sink-in feel sits over AlignSupport coils, giving cushioning with structure beneath it for people who like a plusher surface.
If you prefer sleeping on a firm mattress, this might not be the best choice. Sealy describes the comfort as soft and cosy with a sink-in feel, and doesn't publish a firmness rating. Heavier sleepers, and front sleepers who want flat, unyielding support, may find it gives too much. It's also a premium mattress.
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
How firm is the Sealy Posturepedic Sorrento Plush Combination?
Sealy doesn't publish a firmness rating, but it describes the comfort as soft and cosy with a sink-in feel. That suits people who like a plush surface, although anyone wanting a firm mattress will probably find it too soft.
How deep is the Sealy Posturepedic Sorrento Plush Combination?
It's 33cm deep. That's worth checking against your bed frame and any fitted sheets you plan to use, as deeper mattresses sometimes need deep-fit bedding.
What sizes does the Sealy Posturepedic Sorrento Plush Combination come in?
It comes in a UK single, UK double, UK king and UK super king. Sealy doesn't list a UK small single or UK small double for this mattress, so check the size you need is available.
Is the Sealy Posturepedic Sorrento Plush Combination good for hot sleepers?
It has some features aimed at heat: cooling INFUSE Black Diamond Graphite foam and a breathable cover. That should help, although a soft, sink-in feel can still hold some warmth around your body.
Does the Sealy Posturepedic Sorrento Plush Combination come with a trial?
Dreams offers a 100-night comfort guarantee with this mattress. That's the retailer's own offer rather than Sealy's, so check Dreams' terms before you buy.
