Assessed from the specification published by Archers Sleepcentre, captured September 2026, and from regular price comparison across our UK retail partners.
This is a sensible pick if you want a traditional sprung mattress at a modest price. Prices start from £139.27, which puts it firmly in budget territory, yet the spec includes hypo-allergenic white fibre fillings, Tencel for temperature regulation and a rod-edge wire around the border, which means you can sit or sleep near the edge without it collapsing over time. The open coil system moves as one unit, so it's durable, although couples may notice more motion transfer than with pocket springs. Archers Sleep Centre, the retailer listing this model, offers a 60-night trial (with purchase of a Purecare mattress protector) and a 5-year warranty, made up of a 1-year guarantee plus a 4-year manufacturing warranty.
Key Features & what's inside
- 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.

Who's it NOT for?
Couples who are easily disturbed by movement, since the interconnected open coil system transfers motion more than pocket springs. Firmness feedback is mixed too: some owners found it firmer than expected while one found it softer, so if you need a precise feel, a mattress with a more consistent reputation may suit better.
Highgrove Solar Supreme Mattress
Across 73 reviews on Archers Sleep Centre, the Solar Supreme holds a 4.9 out of 5 rating, with owners praising comfort, value for money, delivery speed and its suitability for side and back sleeping. Some note it feels firmer than expected, though one September 2024 reviewer found it softer than the medium to firm description, so expectations do vary.

How firm is the Highgrove Solar Supreme mattress?
It's described as medium to firm, a suitable level of support for those who can't choose between medium and firm but want a comfortable mattress that's not too hard. Owner feedback varies slightly: some found it firmer than expected, while one reviewer felt it was softer than described.
Does the Highgrove Solar Supreme come with a trial or guarantee?
Archers Sleep Centre lists a 60-night trial, which requires purchase of a Purecare mattress protector, plus a 5-year warranty made up of a 1-year guarantee and a 4-year manufacturing warranty. These are the retailer's terms, so check what applies if you buy elsewhere.
Is the Highgrove Solar Supreme good for hot sleepers?
It should help. The fillings contain Tencel, eucalyptus treated fibres that improve heat flow and moisture dissipation, and the stretch knit cover is breathable. It's not a specialist cooling mattress, but fibre and spring builds like this generally run cooler than all-foam designs.
What sizes does the Highgrove Solar Supreme come in?
Six UK sizes: Small Single, Single, Small Double, Double, King and Super King. Prices range from £139 to £278 depending on the size you choose, starting from £139.27.
How deep is the Highgrove Solar Supreme mattress?
It's 25cm deep, a fairly standard depth that should suit most fitted sheets without any struggle. The height comes from high loft white fibre fillings sitting over the open coil spring unit.
