Why should you choose this mattress?
This is a firm mattress with a bit of comfort built in. The latex layer moves with you, which means it eases pressure rather than feeling like a board. Underneath, PostureTech Core Support Plus springs with 6 turns per spring give the firm support, and the UniKey edge system gives you a larger usable sleep surface, so you can use more of the bed. The SilverFresh cover has an antibacterial finish, and ProShield allergen protection carries an Allergy UK endorsement. It suits most back sleepers, although lighter side sleepers may find it a little firm.
Key features & layer details
Latex comfort layer
A latex layer that moves with you, which means instant pressure relief while the firm feel stays underneath.
Sealy firm foam layer
A double layer of Sealy's firm premium foam that completes the comfort stack, which means a steady, supportive feel above the springs.

Best suited for?
Back sleepers
The firm pocket spring support gives a flat, supportive feel, while the latex comfort layer adds a little give so it doesn't feel like a board.
Allergy sufferers
ProShield allergen protection carries an Allergy UK endorsement, and the SilverFresh cover has an antibacterial finish, which suits anyone wanting a cleaner sleep surface.
Couples
The UniKey edge system gives a larger usable sleep surface, which means you can both use more of the bed, and it comes up to UK super king.
Combination sleepers
The latex layer moves with you as you change position, while the firm springs underneath keep the surface steady and supportive whichever way you turn.
If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It's rated firm, and the latex layer adds only some give on top. Lighter side sleepers may find it hard at the shoulders and hips. It can't be flipped either, so you're limited to rotating it.
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 PostureLux Wilton Mattress?
It's rated firm. The latex comfort layer adds some give on the surface, but the overall feel is supportive rather than plush. It suits sleepers who want firm support, though anyone wanting a softer feel should try something gentler.
What sizes does the Sealy PostureLux Wilton Mattress 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 before you buy.
How deep is the Sealy PostureLux Wilton Mattress?
It's 29cm deep. That's a fairly substantial mattress, so check that your bed frame and bedding suit that depth, especially if the frame has a tall headboard or a shallow recess.
Does the Sealy PostureLux Wilton Mattress have a trial or guarantee?
Dreams offers a 100-night trial, which is the retailer's own offer rather than Sealy's. Sealy gives a 5-year guarantee on the mattress. Check Dreams' terms for returns details before you order.
Is the Sealy PostureLux Wilton Mattress good for allergy sufferers?
It has ProShield allergen protection, which carries an Allergy UK endorsement, plus a SilverFresh antibacterial cover finish. That's a sensible choice if allergens are a concern, although it won't suit anyone who wants a softer mattress.
