Highgrove Solar Ortho Dream Extra Long Mattress

Assessed from the specification published by Archers Sleepcentre, captured September 2026, and from regular price comparison across our UK retail partners.

The main draw is straightforward firm support without a foam-heavy build. The open coil unit with its rod edge wire gives a stable, supportive feel across the whole surface, and the hand tufting keeps the fillings anchored so they are less likely to shift over time. The Tencel treated, hypo-allergenic fillings help with moisture and are a reassuring touch if you're sensitive to allergens. It's good value rather than luxury, and that's fine: you're paying for a sturdy traditional construction, not memory foam layers. Archers Sleep Centre lists a 5 year warranty, described as a 1 year guarantee plus a 4 year manufacturing warranty.

Back sleepers
The connected hourglass spring unit gives a firm, uniform feel across the surface, which suits anyone who likes to lie flat on a properly supportive mattress.

Front sleepers
Firm open coil support with no memory foam layers means your body stays level on top rather than sinking into the mattress.

Allergy sufferers
Hypo-allergenic white fibre fillings treated with Tencel eucalyptus fibres give a clean-feeling, breathable comfort layer that suits anyone sensitive to allergens.

Budget buyers
Described as good value rather than luxury, it puts the money into a sturdy traditional sprung build instead of pricey foam layers.

Heavier sleepers
A thick rod edge wire and a single connected spring unit keep the edges and surface stable, so the mattress holds its shape under more weight.

This is an extra firm mattress, so lightweight side sleepers will likely find it too hard on the shoulders and hips. Because the open coil springs are connected into one unit, couples may notice more movement transfer than with pocket springs, and there are no memory foam layers for a contouring, sink-in feel.

How firm is the Highgrove Solar Ortho Dream mattress?

It's rated extra firm, and owner reviews largely back that up, praising the firmness and back support. That said, a few reviewers found it a little softer than they expected for an extra firm rating, so if you need the absolute hardest surface available, temper expectations slightly.

How deep is the Highgrove Solar Ortho Dream Extra Long mattress?

The Archers Sleep Centre listing is inconsistent here: the description says 25cm while the specifications table and dimensions show 27cm. Either way it's a mid-depth mattress, so standard fitted sheets should work, but check with the retailer if the exact depth matters to you.

Does the Highgrove Solar Ortho Dream come with a guarantee?

Archers Sleep Centre lists a 5 year warranty, made up of a 1 year guarantee plus a 4 year manufacturing warranty. As this appears on a retailer's listing rather than the brand's own site, confirm the exact terms with whichever retailer you buy from.

What sizes does the Highgrove Solar Ortho Dream Extra Long come in?

It's currently listed in EU Single only. It's also a made to order product, so allow for that when planning delivery. If you need a UK standard size or a double, this particular model won't suit.

Is the Highgrove Solar Ortho Dream good for allergy sufferers?

It should help. The fillings are hypo-allergenic white fibre with Tencel eucalyptus treated fibres, which resist the conditions allergens thrive in, and there's no wool or other animal-derived filling listed. It's a sensible pick if dust sensitivity is a concern, although no mattress can eliminate allergens entirely.
