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.
Layer details from mattressnextday.co.uk product page, September 2026.
- Distance beats any comfort layer: The 1,000 pocket springs already limit motion transfer, and 90cm each on top of that means a fidgeting partner becomes genuinely easy to ignore.
- Room for night-time visitors: When a child pads in at 3am, the UK super king's 180cm width means everyone keeps a real share of the bed rather than clinging to an edge.
- Firm support across the full width: The firm feel stays consistent edge to edge, so whoever ends up on the outer third still gets proper support under back and hips.
- Cooler with more space: Geltex is built to let air move, and with 90cm each you're less likely to share body heat, a helpful pairing for warm sleepers.
- Fills a larger master properly: In a period property or generous new build main bedroom, a UK king can look undersized; at 6ft x 6ft 6in this size sits in proportion.
This size suits you if...
You share the bed every night and one of you is a restless sleeper, or children and pets treat your bed as their own and you want everyone to fit without anyone hanging off the side. It also suits you if your master bedroom is large enough that a smaller mattress would look lost, and you can allow at least 3m x 2.9m of floor space.
Consider another size if...
Your room is under our suggested 3m x 2.9m minimum, or the mattress won't make the turn on your landing. The UK king is 30cm narrower and the same length, and we suggest at least 2.7m x 2.9m for it.

Will a super king Sealy Enhance Chrome fit in my bedroom?
The mattress measures 180 x 200cm, or 6ft x 6ft 6in. We suggest a room of at least 3m x 2.9m so you can still open drawers and walk round the bed comfortably. In a smaller room it will dominate, and you may struggle to fit bedside tables on both sides.
Is the super king worth it over the king for this mattress?
If one of you sleeps restlessly, yes. The pocket springs reduce motion transfer, but the extra 30cm of width over the UK King does more than any spring design can: with 90cm each for two people sharing, most movement simply happens too far away to wake you.
Is the Sealy Enhance Chrome super king good for sharing with children or pets?
It's one of the better setups for it. The firm surface holds its shape under extra bodies, and 180cm of width means a wandering child or a large dog doesn't push either adult to the edge. Lightweight children lying on their side may find the surface a little solid, though.
Can you get a super king mattress upstairs?
Usually, but this is the size where door swings and landing turns start to bite. At 180 x 200cm and 26cm deep, the Sealy Enhance Chrome is a bulky, fairly rigid item to manoeuvre, so measure your stairwell, any tight turns and the bedroom door before ordering.
Where can I buy the Sealy Enhance Chrome in a super king?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so it's worth checking back if you're not buying straight away. Stock of the largest sizes can be patchier than the UK double or UK king, so availability may shift.
