Highgrove Solar Comfort Mattress
The Highgrove Solar Comfort is a simple, budget-friendly mattress built around open coil springs with white fibre fillings, which means a traditional, slightly bouncy feel rather than the contouring of memory foam.

The Highgrove Solar Comfort is rated Medium in firmness and comes in at 20cm deep, a little shallower than many modern mattresses, so it suits divans and slatted frames without towering over them. It comes in five UK sizes, from Small Single to King. It's an entry-level buy: no clever cooling tech or pocket springs, but a sensible option for a spare room, a child's bed or anyone who wants straightforward comfort without spending much.

Why should you choose this mattress?
Choose the Solar Comfort if your priority is price. It delivers a Medium feel that suits most back and combination sleepers, and the open coil unit with its wire edge border gives the mattress structure and helps it hold up over time. Buying through Archers Sleep Centre, the listing includes a 60-night comfort guarantee and a 5-year warranty, though these are the retailer's own terms and require purchasing a Purecare mattress protector to qualify. Delivery is free to UK mainland addresses on a day of your choice, with a charge for remote locations and islands. If you want a low-cost, no-fuss mattress for occasional or everyday use, this fits the brief.
Key features & layer details
Stitchbond Cover
A hard-wearing polyester fabric with a quilted finish, which keeps costs down without feeling flimsy. The stitching attaches the outer fabric to the surface fillings, which means a flat, even sleeping surface rather than one that shifts about.
White Fibre Fillings
A lightweight, high-loft filling that's hypoallergenic and holds its shape well. You get a soft initial feel, and the fibres are designed to keep their comfort over time.
Open Coil Springs
Rows of hourglass-shaped springs joined at the top and bottom by a spiral helical wire, an interconnected system that's durable and gives a traditional bouncy feel. Because the springs are linked, movement does transfer across the bed more than it would with pocket springs.
Wire Edge Border
A thick wire runs around the perimeter of the spring unit, which means firmer edges and a longer-lasting mattress. It also helps you use the full width of the bed without the sides sagging.

Best suited for?
Back sleepers
The Medium firmness gives a balanced feel, and the wire edge border and open coil unit keep the surface structured under the hips and shoulders.
Combination sleepers
A Medium feel and a quilted Stitchbond cover create a flat, even surface, so changing position through the night doesn't feel like moving over a shifting top.
Guest rooms
Sensible for a spare room, since the simple open coil build keeps costs down and the 20cm depth sits neatly on most divans.
Allergy sufferers
The white fibre fillings are described as hypoallergenic and hold their shape well, giving a soft initial feel without relying on natural fillings.
Budget buyers
As an entry-level mattress with no pocket springs or cooling extras, it keeps things simple for anyone wanting straightforward comfort without spending much.
If you share a bed and your partner tosses and turns, the interconnected coils will telegraph that movement, so pocket springs would suit you better. At 20cm deep with fibre fillings, it also offers less cushioning than plusher mattresses, so heavier sleepers or dedicated side sleepers may want more depth and contouring.
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
Is the Highgrove Solar Comfort mattress firm or soft?
It's rated Medium, which suits most back and combination sleepers. The open coil springs give a traditional, slightly bouncy feel, while the white fibre fillings add a soft surface layer. Lightweight side sleepers may find it comfortable enough, though anyone wanting deep contouring should look at foam or hybrid designs instead.
How deep is the Highgrove Solar Comfort mattress?
It's 20cm deep, which is on the shallower side by modern standards. That's not necessarily a drawback: it works well on divans, slatted frames and bunk beds, and standard fitted sheets will fit easily. Heavier sleepers who need more material beneath them may prefer something deeper.
Does the Highgrove Solar Comfort come with a trial or warranty?
Archers Sleep Centre lists a 60-night comfort guarantee and a 5-year warranty on this mattress. Both are the retailer's own offers rather than Highgrove's, and their terms include buying a Purecare mattress protector to qualify. If you buy elsewhere, check what that seller offers, as these terms won't automatically apply.
What sizes does the Highgrove Solar Comfort mattress come in?
Five UK sizes: Small Single, Single, Small Double, Double and King. The Small Single and Small Double options are handy for box rooms and guest beds where a standard size won't quite fit.
Is delivery free for the Highgrove Solar Comfort?
Archers Sleep Centre offers free day-of-choice delivery to UK mainland addresses. If you live in a remote location or on an island, a delivery charge applies, so it's sensible to check the cost for your postcode before ordering.
