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.

Key benefits
- A one-person size where open coil makes sense: The interconnected springs transfer movement across the bed, which matters for couples, but with a single sleeper there's nobody on the other side to disturb.
- Fits compact rooms: At 90cm wide (3ft x 6ft 3in overall), it leaves floor space for a desk, wardrobe or toy storage, and we suggest allowing at least 2.1m x 2.8m.
- Rod-edge support for restless kids: A thick wire around the perimeter springs stops the border breaking down, useful when a child sits on the edge every morning or sleeps right against it.
- Tencel fillings for warm sleepers: Eucalyptus treated fibres improve heat flow and wick moisture, which means a teenager who runs hot should sleep a little cooler than on a basic fibre-topped mattress.
- Hypo-allergenic fillings: The white fibre fillings suit allergy-prone children and guests, and the micro quilted cover keeps the surface smooth rather than bunching.
This size suits you if...
You're buying for a child or teenager moving up to a full-size bed, you need a dependable mattress for a spare room that only sees guests a few nights a year, or you're a single adult in a compact room who wants a supportive sprung feel without spending much. The medium to firm feel suits most solo sleepers, although very lightweight side sleepers may find it slightly firm.
Consider another size if...
You're an adult who shares the bed regularly, or you simply want more space to spread out. At 90cm wide the UK single is 45cm narrower than the UK double, so we'd recommend the Highgrove Solar Supreme in a UK double instead.

FAQ's
Is the Highgrove Solar Supreme UK single suitable for a bunk or mid sleeper frame?
Possibly, but check your frame first. This mattress is 25cm deep, and raised frames set a maximum mattress depth so the guard rail still sits high enough above the sleeping surface. Measure from the base to the top of the rail before buying; for some bunks, 25cm will be too deep to be safe.
Will two Highgrove Solar Supreme UK singles fit in one shared room?
Often, yes. Each mattress is 90 x 190cm, and we suggest allowing at least 2.1m x 2.8m of floor space for one single, so a shared room needs comfortably more than that to leave a walkway between the beds. Sketch the layout with wardrobes and desks included before committing to two.
Is the Highgrove Solar Supreme UK single a good choice for a guest room?
It's well suited to occasional guests. The rod-edge wire keeps the border supportive even with infrequent use, the hypo-allergenic fillings suit visitors with sensitivities, and single bedding is the cheapest and most widely stocked. Two singles also work well in a spare room set up for flexible guest arrangements.
How much narrower is a UK single than a small double?
The UK single is 30cm narrower than the UK small double. That extra width is the main reason single adults size up: the small double gives a solo sleeper noticeably more room to spread out, while the single frees more floor space in a tight room. For a child or teen, the single is usually the practical pick.
