Choose this if you need a firm mattress in an EU Single size at a modest price. The open coil interior is connected into a single unit by a helical wire, which means the whole spring system moves together and gives that classic, firm, uniform feel. A rod edge wire runs around the perimeter, which means you can sleep right up to the edge without the border sagging over time. The fibre fillings are hypo-allergenic and hold their shape, a sensible choice if dust or allergies bother you. Archers Sleep Centre lists a 5-year warranty, made up of a 1-year guarantee plus a 4-year manufacturing warranty, along with free day of choice UK delivery.
Key Features & what's inside
- Damask Cover. A quality damask cover with a micro quilted finish, which secures the cover to the surface layers beneath it. In practice that means a smooth, even sleeping surface with fillings held firmly in place.
- White Fibre Fillings. A lightweight, high loft fibre that retains its shape over time, which means less of the dipping you can get with softer fillings. It's also hypo-allergenic, a plus for allergy-prone sleepers.
- Open Coil Springs. Hourglass shaped springs connected into one single unit by a spiral helical wire. This gives a firm, traditional feel, although it does mean movement transfers across the mattress more than with pocket springs, so it suits solo sleepers best.
- Wire Edge Border. A thick rod edge wire attached to the perimeter of the spring unit, which means you get full use of the mattress width. It also helps prevent the border breaking down where you sit or roll near the edge.

Who's it NOT for?
If you're a lightweight side sleeper, a firm open coil mattress may feel too unyielding on your shoulders and hips. It's also not ideal for couples, as the connected spring unit transfers movement, though as a single that's rarely an issue. And if you want deep, cushioned comfort layers, this simple fibre-filled build won't provide them.

How firm is the Highgrove Solar Backcare mattress?
It's rated firm. The open coil springs are connected into one unit, which gives a solid, uniform feel across the whole surface. That suits back sleepers and anyone who prefers a supportive base, although lighter side sleepers may find it a little unforgiving.
What size is the Highgrove Solar Backcare Extra Long mattress?
It's available as an EU Single. Archers Sleep Centre's specification lists it at 90cm wide, 200cm long and 23cm deep, though the listing's description also mentions a 206cm length, so it's sensible to confirm the exact length with the retailer before ordering, particularly for a specific bed frame.
Does the Highgrove Solar Backcare come with a warranty?
Archers Sleep Centre lists a 5-year warranty, made up of a 1-year guarantee plus a 4-year manufacturing warranty. As this is stated on a retailer listing rather than the manufacturer's own page, check the terms at your point of purchase.
Is the Highgrove Solar Backcare good for allergies?
The comfort layer uses white fibre fillings, which are hypo-allergenic and hold their shape well. That makes it a reasonable pick if dust or allergens are a concern, though as with any mattress a washable protector is still a good idea.
How much does the Highgrove Solar Backcare cost?
Prices run from £154 to £155, starting at £154.44 from one listed retailer. That's an affordable price, and it reflects the simple construction: open coil springs and fibre fillings rather than pocket springs or memory foam.
