Layer Details
- Cover. A soft stretch knit fabric with a micro quilted finish, which secures the outer fabric to the surface layers. In practice that means the top stays smooth and in place rather than shifting or bunching.
- Fillings. White fibre fillings that are lightweight, high loft and hypo-allergenic, which means they hold their shape well and suit allergy-prone sleepers. Tencel, a eucalyptus treated fibre, is blended in to improve heat flow and wick away moisture, helpful if you tend to sleep warm.
- Spring System. Hourglass shaped springs set in head-to-toe rows, connected by spiral wires into an interconnected open coil unit. This is a hardwearing, traditional design, although it does transfer more movement across the bed than pocket springs, so a restless partner will be more noticeable.
- Edge Support. A thick rod-edge wire attached to the perimeter springs to prevent border breakdown. You'll feel this as edge to edge support, so sitting on the side of the bed or sleeping near the edge won't cause early sagging.

- The classic couples' footprint: At 135 x 190cm (4ft 6in x 6ft 3in), the UK double is the long-standing standard for two, with 67.5cm each for two people sharing.
- Fits rooms a king would dominate: We suggest allowing at least 2.6m x 2.8m, which most UK bedrooms manage while still keeping bedside tables on both sides.
- Edge support matters more at this width: The rod-edge wire keeps the border firm, which means two sleepers can each use the full 67.5cm of their side without rolling off a sagging edge.
- Easy to dress on a budget: Double sheets and duvets are stocked everywhere at every price, useful if this mattress is one line on a long furnishing list.
- A practical guest room choice: A UK double works for visiting couples and solo guests alike, and this straightforward open coil build suits a bed that isn't slept in every night.
This size suits you if...
You're a couple happy with the traditional shared size, your bedroom sits around our suggested 2.6m x 2.8m minimum, or you're kitting out a guest room or a first home and want a dependable sprung mattress without spending much. It also suits a solo sleeper who likes room to spread out, though the interconnected springs matter less when there's no partner to disturb.
Consider another size if...
You share the bed every night and either of you sleeps restlessly, since the open coil unit passes movement across the bed and 67.5cm each is snug. If your room allows it, we'd recommend the UK king instead for the extra 15cm of width.

Is the Highgrove Solar Supreme UK double big enough for two people?
It works for most couples, with 67.5cm each for two people sharing. That's the traditional standard rather than generous, and because the open coil springs are interconnected, you'll feel a partner's movement more than you would on pocket springs. The UK king is 15cm wider than the UK double if you want more room.
What room size do I need for the Highgrove Solar Supreme in a double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves walking space and room for bedside tables on both sides. The mattress itself is 135 x 190cm, so measure your floor plan with wardrobes and drawers marked in before deciding.
Should I choose the Highgrove Solar Supreme in a UK double or a UK king?
The UK double is 15cm narrower than the UK king, so it suits smaller rooms and tighter budgets. Because this mattress transfers motion across its interconnected springs, couples who wake easily may find the extra width of the UK king softens that effect. Solo sleepers rarely need to size up.
Does the double Highgrove Solar Supreme suit a guest room?
Yes, arguably better than most sizes. A UK double accommodates visiting couples and single guests alike, the open coil unit is a hardwearing design for occasional use, and double bedding is cheap and easy to find. The rod-edge wire also helps guests who perch on the side of the bed.
What bedding fits the Highgrove Solar Supreme double?
Standard UK double sheets, sized for a 135 x 190cm mattress, and a 200 x 200cm double duvet. Both are the most widely stocked bedding sizes in Britain, available at every price point, which keeps running costs down if you're furnishing a whole home at once.
