Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw is temperature. Geltex foam has an open-cell structure, which means air moves through it rather than being trapped, so it should feel cooler than a traditional memory foam hybrid. Underneath, 1000 pocket springs move independently, adapting to your body rather than pushing back as one unit. That helps with pressure relief and reduces the ripple you feel when a partner turns over. The knitted cover adds a soft, breathable finish. If you're a hot sleeper who still wants the responsive feel of springs, this is a solid, fairly priced option. Buying through Mattress Online, you also get a 100-night trial and free delivery to most locations, which takes some of the risk out of ordering online.
Key Features & what's inside
- Knitted cover. A soft knitted sleeping surface that adds a touch of cosiness and warmth. Knitted covers are also breathable, so air can pass through rather than building up around you.
- Geltex. A breathable foam layer with an open-cell structure, which means heat escapes rather than being held against your body. It's designed for a cooler night's sleep than conventional foams.
- Pocket springs. Individual springs encased in cloth pockets that adapt to your movement independently. This gives each part of your body its own level of support and helps limit motion transfer between partners.

Who's it NOT for?
If you sleep best on a firm mattress, Sealy's own medium rating suggests this will feel softer than you'd like. Heavier sleepers wanting a denser spring unit, or anyone after a natural-fibre mattress rather than foam, may also be better served elsewhere.
Sealy Hampton Geltex Enhance 1000 Pocket Mattress
How firm is the Sealy Hampton Geltex Enhance 1000?
Sealy rates it as medium, although you may see it listed as medium firm elsewhere. In practice that means a balanced feel that suits most sleeping positions, with enough give for side sleepers and enough support for back sleepers.
Does the Sealy Hampton Geltex Enhance sleep cool?
It should sleep cooler than many foam hybrids. The Geltex layer has an open-cell structure that lets heat and air pass through, and the knitted cover is breathable too. If you tend to overheat at night, this construction works in your favour.
Does the Sealy Hampton Geltex Enhance come with a trial?
Mattress Online lists a 100-night trial with this mattress. That's the retailer's own offer rather than a Sealy guarantee, so check the terms if you buy from a different shop.
How deep is the Sealy Hampton Geltex Enhance 1000?
It's 25cm deep, a fairly standard depth that should work with most fitted sheets. It's available in UK Single, Double, King and Super King sizes.
What guarantee does the Sealy Hampton Geltex Enhance have?
The Mattress Online listing states a 5-year guarantee. The mattress is handcrafted in the UK and Sealy is a National Bed Federation Approved Brand, which offers some reassurance on manufacturing standards.
