Highgrove describes the Solar Supreme as medium to firm, a middle ground for people who can't decide between the two, which means a supportive feel without being hard on the shoulders and hips. The fillings include Tencel, eucalyptus treated fibres that improve heat flow and moisture dissipation, so it should sleep a little cooler than a basic fibre-topped mattress. It's a straightforward, traditional build rather than a pocket sprung or memory foam design, and the price reflects that.

Why should you choose this mattress?
This is a sensible pick if you want a traditional sprung mattress at a modest price. Its starting price 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 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 & 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.

Best suited for?
Budget buyers
The copy places it firmly in budget territory while still including hypo-allergenic fibre fillings, Tencel and a rod-edge wire, so you get a fuller spec than the entry level suggests.
Allergy sufferers
White fibre fillings that are hypo-allergenic and hold their shape well make this a sensible choice if you tend to react to bedding.
Warm sleepers
Tencel, a eucalyptus treated fibre, is blended into the fillings to improve heat flow and wick away moisture, which should help you stay cooler overnight.
Guest rooms
A rod-edge wire around the border stops the sides breaking down early, so visitors can sit or sleep near the edge without it sagging.
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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
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.
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.
