Choose the Waltham if you like a responsive surface rather than a sinking, hug-you feel. The latex filling offers pressure relief while springing back quickly, and the PostureTech springs beneath add zoned support, which means your hips and shoulders should stay reasonably aligned. Sealy's EdgeGuard reinforces the sides, so you can use the full width of the bed without feeling like you might roll off. The medium firmness suits most sleepers, although anyone who prefers a very firm surface may find it a little soft. At £499 for a UK Single, it's an accessible way into latex, a material that tends to sit at higher prices.
Key Features & what's inside
- Cover. A smooth quilted surface in knit fabric. It gives the sleeping surface a soft, finished feel from the first night.
- Filling. A latex filling that provides pressure relief with a resilient, bouncy feel. In practice, that means cushioning for your hips and shoulders without the stuck-in sensation some foams create.
- Spring System. Sealy's proprietary PostureTech spring system, built for even weight distribution and zoned support. Different areas of the mattress respond differently, so heavier parts of your body get firmer backing.
- Edge Support. Sealy's EdgeGuard extends the usable sleeping area and supports durability. You can sit or sleep near the edge without the sides collapsing.

Who's it NOT for?
If you prefer a firm or very soft mattress, the medium feel here won't suit. Sleepers who like the slow, cradling sink of memory foam may find latex too springy. And if you need a bed quickly, Furniture Village's estimated delivery of up to 5 weeks is a genuine wait.
Sealy Waltham Mattress
How firm is the Sealy Waltham mattress?
It's a medium. That suits most sleepers, including back and side sleepers who want a balance of cushioning and support, although those who like a distinctly firm surface may find it a little soft.
Does the Sealy Waltham need turning?
No, it doesn't require turning. That makes it easier to live with, particularly as latex mattresses can be heavy to handle.
What guarantee comes with the Sealy Waltham?
Furniture Village lists a 20 year structural guarantee for this mattress, which is a longer span than most brands offer. Check the terms at the retailer you buy from, as cover can vary between sellers.
How much does the Sealy Waltham cost?
Prices range from £499 to £849 depending on size, starting at £499 for a UK Single. It's also available in Double, King and Super King. For a latex mattress with a pocket-sprung style support system, that's honest value.
How thick is the Sealy Waltham mattress?
It's 29cm deep, a substantial depth that should work with most fitted sheets, though extra-deep sheets may fit more comfortably.
