Layer Details
- Cover. A FabriSafe cover made from wool yarn and viscose fabric, which is naturally fire retardant with zero chemical treatments. That means it meets safety standards without sprayed-on chemicals near your skin.
- Comfort Layer. Traceable British wool paired with recycled polyester fibres for cushioning. Wool helps regulate temperature, so it works across warmer and cooler nights.
- Support System. 750 Cortec Quad steel pocket springs, each in its own fabric pocket, welded together ultrasonically and completely glue-free. Individual pockets mean the springs respond to your shape rather than moving as one block.

- Movement stays on your side: Each of the 750 Cortec Quad springs sits in its own pocket, which means your partner's midnight shuffle stays under them rather than travelling across the bed.
- Fits rooms a king would crowd: At 135cm wide, it leaves space for bedside tables on both sides in a typical UK bedroom; allow at least 2.6m x 2.8m.
- Wool that suits two body heats: Traceable British wool in the comfort layer helps regulate temperature, useful when two people sharing 135cm inevitably warm the bed faster than one.
- Easy to dress on a budget: Double sheets and duvets are stocked everywhere at every price, a quiet saving if you're furnishing a whole home at once.
- A medium feel for two different sleepers: The medium tension aims at the middle ground, which makes it a sensible compromise when two people with different preferences share one mattress.
This size suits you if...
You share the bed every night and want the traditional couples' size in a room where a UK king would dominate, you're kitting out a first flat or a guest room for visiting couples without stretching the budget, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner.
Consider another size if...
You both want more personal space and your room can take a bigger bed. The UK king is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m, and we'd recommend it if that fits.

Is the Harrison Spinks Luxury Essential 750 in a UK double wide enough for a couple?
Yes, though it's the snuggest of the standard couples' sizes: 67.5cm each for two people sharing. The 750 pocket springs help here, because each spring responds independently and your partner's movement stays largely on their side. If either of you sprawls, or you share with a pet, the UK king gives noticeably more room.
What room size do I need for this mattress 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. In an older terrace or a compact new build, measure the landing and any turns on the stairs before ordering, as a 135 x 190cm mattress needs to get up there.
Should I buy the UK double or the UK king in this mattress?
The UK double is 15cm narrower and 10cm shorter than the UK king. If you share every night and your room meets our suggested 2.7m x 2.9m minimum for the UK king, sizing up is usually money well spent. If space is tighter, or the bed is for a guest room, the UK double is the sensible pick.
How big is the Harrison Spinks Luxury Essential 750 UK double in feet and inches?
It measures 4ft 6in x 6ft 3in, which is 135 x 190cm. That's the long-standing UK standard for two people sharing, and it takes standard double sheets and a 200 x 200cm double duvet, both easy to find at any price point.
Where can I compare prices for this mattress in a UK double?
The retailer prices listed on this page are live and updated as retailers change them, so compare them here rather than relying on a figure you saw last week. Stock and pricing for individual sizes can shift quickly, and the UK double is typically the most widely stocked size of any UK mattress.
