Assessed from the specification published by Archers Sleepcentre, captured September 2026, and from regular price comparison across our UK retail partners.
You'd choose the Edmonton for its price and its length. It's listed from £164.38, and the EU Single sizing gives extra length over a standard UK single, useful for taller teenagers or growing children. The medium firmness suits most sleeping positions, although very heavy sleepers may want something more supportive. Being double-sided helps longevity, since flipping spreads the wear across both surfaces. Archers Sleep Centre lists free day-of-choice UK delivery and a 1-year guarantee, though those are the retailer's own terms, not the brand's, so they may differ elsewhere. If you want deep contouring or strong edge support, this isn't that mattress, but as an honest budget sprung option it does its job.
Key Features & what's inside
- Stretch Knit Fabric. A soft, pliable cover that lets the fillings beneath contour to your body shape. In practice, that means the surface follows you rather than fighting you.
- Quilted Finish. The outer fabric is stitched to the surface fillings, which keeps the sleeping surface flat and even. You get a smooth, traditional quilted feel with no loose padding shifting about.
- White Fibre Fillings. A lightweight, high-loft filling that holds its shape well over time. It's hypoallergenic too, a small reassurance if you're prone to allergies.
- High-density advanced foam comfort layers. A reflex foam layer that conforms to your body by distributing weight evenly, which means fewer pressure points at your hips and shoulders. It's a firmer, springier foam than memory foam, so you won't feel stuck in it.
- Open Coil Springs. Hourglass-shaped springs joined top and bottom by spiral helical wires, forming one interconnected unit. This gives a durable, traditional bounce, though connected springs do transfer a little more movement than pocket springs.

Who's it NOT for?
Skip this one if you need a standard UK size: it comes in EU Single only, so measure your frame first. It's also a little less suited to those who sit or sleep near the edge, as some owner reviews mention edge support could be better given the vacuum-packed design.
Highgrove Edmonton Extra Long Mattress
View all mattresses
How firm is the Highgrove Edmonton mattress?
It's listed as medium, which suits most sleepers and most sleeping positions. The reflex foam comfort layer softens the open coil springs beneath, so you get gentle cushioning with a supportive sprung base rather than an outright firm feel.
What size is the Highgrove Edmonton Extra Long mattress?
It's available in EU Single only, which is longer than a standard UK single. That extra length is handy for taller sleepers, but do check it fits your bed frame before ordering, as UK frames won't always accommodate EU sizing.
Does the Highgrove Edmonton come with a guarantee?
Archers Sleep Centre lists a 1-year guarantee with this mattress. That's the retailer's own offer rather than a brand-wide promise, so if you buy elsewhere the terms may differ. It's a shorter cover period than many mattresses carry, which reflects the budget price.
Can you flip the Highgrove Edmonton mattress?
Yes, it's double-sided, so you can flip it to spread wear across both surfaces. Regular flipping and rotating should help it keep its shape for longer, which matters more with fibre-filled mattresses like this one.
How is the Highgrove Edmonton delivered?
It arrives vacuum-packed, rolled for easier handling into the bedroom. Archers Sleep Centre offers free day-of-choice UK delivery, though that's the retailer's own service and won't necessarily apply if you buy from another shop. Some owner reviews note the vacuum packing affects edge support slightly.
