Why should you choose this mattress?
The Memory Flex comfort layer gives you the contouring of memory foam, while the Align Support coil underneath is there to keep the support steady. The medium grade is a sensible middle ground that should suit most sleepers, although very heavy or very light sleepers may want something different. UniCased XT edge support with air channels helps the edges hold up when you sit or sleep near them. The SmarTex Plus cover, made with Tencel fibres, regulates temperature. ProShield allergen protection is included, and the mattress is endorsed by Allergy UK.
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 SmarTex Plus cover is made with Tencel fibres and regulates temperature, which helps the bed feel comfortable if you tend to get hot overnight.
Allergy sufferers
ProShield allergen protection is built in and the mattress is endorsed by Allergy UK, which gives you a cover designed with allergens in mind.
Couples
UniCased XT edge support with air channels helps the sides hold up, so sitting or sleeping near the edge feels steadier, and a UK king or super king gives room for two.
Combination sleepers
A medium grade with a Memory Flex layer gives some contouring without feeling sunk in, which suits moving between positions through the night.
If you prefer sleeping on a firm mattress, this might not be the best choice. It has a medium comfort grade, so it gives more cushioning than a firm model. It's single-sided and can't be flipped, which means you can't turn it over to even out wear. Sealy doesn't publish a spring count for the coil.
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 Elevate Ultra Antuco Mattress?
It has a medium comfort grade, so it sits in the middle of the firmness range. That suits most sleepers, although anyone who wants a firm, flat feel will probably find it too cushioned.
What sizes does the Sealy Elevate Ultra Antuco Mattress come in?
It comes in a UK single, UK double, UK king and UK super king. There's no UK small single or UK small double, so check your bed frame size before you buy.
How deep is the Sealy Elevate Ultra Antuco Mattress?
It's 34cm deep, which is a deep mattress. Check that your bed frame and fitted sheets can take that depth before you buy.
Can you flip the Sealy Elevate Ultra Antuco Mattress?
No, it's single-sided and isn't designed to be flipped. You can't turn it over to even out wear, so the comfort layers stay on top throughout its life.
Does the Sealy Elevate Ultra Antuco Mattress come with a trial?
Dreams offers a 100-night trial on purchases from Dreams. A 7-year guarantee is also mentioned, but no issuer is named, so check the exact terms with the retailer before you buy.
