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.

Key benefits
- Fits compact rooms: At 90cm wide it leaves floor space free for a desk, wardrobe and toy storage, so a child's bedroom still has room to play.
- Firm support for growing sleepers: The firm pocket spring base gives back and front sleepers steady, even support, a sensible choice for a teenager's first proper mattress.
- Cooler nights in small spaces: Geltex is a gel-infused foam that lets air move through, helpful in a boxy single room or a loft conversion that warms up quickly.
- Easy, cheap bedding: Standard single fitted sheets and duvets are the most widely stocked of any size, and the 26cm depth works with ordinary fitted sheets.
- Guest room ready: A spare room doubling as an office can take a UK single without swallowing the desk, and the firm feel suits occasional guests of most sleeping styles.
This size suits you if...
You're buying for a child or teenager who needs firm, even support, you sleep alone in a compact room where every centimetre of floor matters, or you're kitting out a spare room that also works as an office and want a bed that stays out of the way.
Consider another size if...
You're an adult who spreads out in the night, or a restless sleeper who feels hemmed in at 90cm wide. We'd recommend the UK small double instead, which is 30cm wider and the same length; allow at least 2.4m x 2.8m for it.

FAQ's
What size is the Sealy Enhance Chrome in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. It's the standard one-person size in the UK, so any UK single bed frame, single fitted sheet and single duvet (135 x 200cm) will fit it without hunting for special bedding.
Will the Sealy Enhance Chrome UK single fit a bunk or mid sleeper frame?
The width is right, since bunks and mid sleepers take a standard UK single. The thing to check is depth: this mattress is 26cm deep, and raised frames often specify a maximum mattress depth so the guard rail stays high enough. Check your frame's limit before buying, especially for a top bunk.
Is the Sealy Enhance Chrome single a good choice for a child?
It can be. The firm pocket spring base gives steady support for a growing back, and the quilted top softens the first touch. One caution: lightweight side sleepers may find it a little too solid at the shoulder and hip, so a child who sleeps mostly on their side might prefer something softer.
How much floor space does a UK single Sealy Enhance Chrome need?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves room to walk alongside the bed and open drawers or wardrobe doors. In a child's room it also keeps space free for a desk and storage, and in a loft conversion the 90cm width can slot under the slope where a wider bed wouldn't.
Should I choose the UK single or the UK small double in this mattress?
The UK single is 30cm narrower than the UK small double, and the two are the same length. For a child, a teen or a tight room, the UK single is the practical pick. A solo adult who wants space to stretch out would do better with the UK small double, which needs at least 2.4m x 2.8m of floor space.
