Layer Details
- 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.

- A shared size that fits real rooms: At 135 x 190cm, the UK double leaves space for a wardrobe and drawers in the sort of bedroom where a king would feel cramped.
- Edge support that matters more when sharing: Sealy's EdgeGuard reinforces the sides, so two people can use the full 135cm width without either of you drifting towards a collapsing edge.
- Responsive latex for two sleep schedules: Latex recovers quickly when one of you shifts position, which means less of the rolling-together effect a couple can get on softer foams.
- Zoned springs across a shared surface: The PostureTech spring system distributes weight evenly, useful when two differently sized sleepers share one mattress.
- Bedding is cheap and everywhere: Double sheets and duvets are stocked at every price point, a small but real saving if you're furnishing a whole home at once.
This size suits you if...
You share the bed most nights and want the classic couples' size in a room where a bigger mattress would dominate, or you sleep alone and want space to stretch out, perhaps with a dog or cat claiming a corner. It also makes sense for a guest room that needs to host visiting couples comfortably.
Consider another size if...
You and your partner both want more personal space than 67.5cm each for two people sharing. The UK king is 15cm wider and 10cm longer, and we'd recommend it if your room allows at least 2.7m x 2.9m.

Is the Sealy Waltham double big enough for two adults?
It gives 67.5cm each for two people sharing, which most couples find workable rather than generous. The Waltham's EdgeGuard edge support helps here, letting you both use the full width without the sides giving way. If either of you sleeps starfish-style, the UK king's extra 15cm of width is a genuine upgrade.
What room size do I need for the Sealy Waltham in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. If yours is smaller, measure carefully before committing, as a wardrobe and chest of drawers eat floor space faster than you'd expect.
Should I get the Sealy Waltham in a double or a king?
The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the double if your room is under 2.7m x 2.9m or you want to keep space for other furniture. Choose the king if you share nightly and either of you is tall, since the double's 190cm length is snug past six feet.
Will a double Sealy Waltham fit up narrow stairs?
The latex and spring construction means the Waltham doesn't arrive rolled in a box, so the full 135 x 190cm footprint has to make every turn. In older terraces with tight winders, or new builds with small landings, measure the stairwell and doorways before ordering. Check the retailer's delivery access guidance too.
What bedding fits the Sealy Waltham double?
Standard double fitted sheets for a 135 x 190cm mattress, with a 200 x 200cm double duvet. Check the sheet's stated depth against the Waltham's 29cm profile, as shallower fitted sheets can pop off a mattress this deep. Double bedding is the most widely stocked size in the UK, so replacements are easy to find.
