Why should you choose this mattress?
The main draw here is the combination of a properly firm support base with a gel-infused comfort layer on top, which means you get the stability of a firm mattress without the hard, unyielding surface some firm models have. The 1,000 pocket springs move independently of one another, so when your partner shifts in the night you should feel less of it on your side. Geltex is also built for breathability, a helpful trait if you tend to sleep warm. Add the made-in-the-UK, NBF-approved credentials and a mid-range starting price, and it's a reasonable package for anyone who knows they want firm support.
Key features & layer details
Quilted Cover
The cover and fillings are stitched together into a patterned comfort quilt, which means the top surface feels cushioned and stays in place rather than shifting around. It gives the mattress a soft first touch before you reach the firmer layers below.
Geltex®
Geltex is a gel-infused foam that shapes to your body for pressure relief while remaining breathable, so it shouldn't trap heat the way traditional memory foam can. It sits between you and the springs to soften that firm base.
Pocket Springs
The Chrome has 1,000 individually mounted springs, each sewn into its own fabric pocket so it can move independently of its neighbours. In practice, this means better contouring to your shape and less motion transfer between partners.

Best suited for?
Back sleepers
The firm support base keeps the body held level, while the Geltex comfort layer softens the surface so it doesn't feel hard or unyielding.
Front sleepers
A firm feel stops the hips sinking too low, and the gel-infused Geltex layer on top keeps the surface from feeling harsh against you.
Couples
The 1,000 pocket springs move independently of one another, which means you should feel less of your partner's movement during the night.
Warm sleepers
Geltex is a gel-infused foam built for breathability, so it shouldn't trap heat the way traditional memory foam can.
Combination sleepers
The firm base with a cushioned Geltex layer above suits those who shift between back and front positions, though side sleeping at lighter weights may feel solid.
This is a firm mattress, so lightweight side sleepers are likely to find it too unforgiving at the shoulder and hip. If you prefer a plush, sink-in feel, look elsewhere. And with 1,000 pocket springs, those wanting the deeper contouring of a higher spring count may want to consider other options.
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 Enhance Chrome Pocket Geltex mattress?
It's rated firm. That makes it a good match for back and front sleepers, and for anyone who prefers to sleep on top of a mattress rather than sinking into it. Side sleepers, particularly lighter ones, may find it slightly too firm for comfortable pressure relief.
How many springs does the Sealy Enhance Chrome have?
It contains 1,000 pocket springs, each sewn into its own fabric pocket. Because the springs move independently, they follow your body shape more closely than a traditional open-coil unit and pass on less movement when a partner turns over.
What is Geltex in a Sealy mattress?
Geltex is a gel-infused foam used in the comfort layer. It's designed to deliver body support, pressure relief and breathability, so it cushions you without the heat build-up that solid memory foam can produce.
Does the Sealy Enhance Chrome come with a guarantee?
The MattressNextDay listing states a five-year guarantee from Sealy. It's sensible to confirm the exact terms with your chosen retailer before you buy, as coverage details can differ between sellers.
What sizes does the Sealy Enhance Chrome come in?
Five UK sizes are available: Single, Small Double, Double, King and Super King. The mattress is 26cm deep across the range.
