Why should you choose this mattress?
If you're after a straightforward sprung mattress on a modest budget, the Edmonton makes a sensible case. The medium feel suits most sleepers, although anyone wanting a firmer orthopaedic-style surface may find it a little too forgiving. Open coil springs are an older technology than pocket springs, yes, but they keep the price down and give a slightly bouncier, more connected feel that some people genuinely prefer. The reflex foam comfort layer distributes your weight, which means fewer pressure points at the hips and shoulders. The guarantee cover is short at one year for manufacturing faults, so this is best viewed as a value buy for a spare room or a tight budget rather than a decade-long investment.
Key features & layer details
Stretch Knit Fabric
A soft, pliable cover that lets the fillings beneath contour to your body shape. You feel the comfort layers working rather than a stiff barrier between you and them.
Quilted Finish
The outer fabric is stitched directly to the surface fillings. This keeps everything in place, which means a flat, even sleeping surface without the fillings shifting about.
White Fibre Fillings
A lightweight, high-loft material that holds its shape over time. It's hypoallergenic too, a helpful point if you're prone to allergies.
High-density advanced foam comfort layers
A reflex foam layer designed to conform to your body by spreading your weight evenly. In practice that means reduced pressure points where you sink in most, typically hips and shoulders.
Open Coil Springs
Rows of hourglass-shaped springs joined at top and bottom by helical wires, forming one interconnected unit. This construction is hardwearing, though the connected springs mean you'll notice a partner's movement more than you would with pocket springs.

Best suited for?
Budget buyers
Open coil springs keep the cost down, which means you get a straightforward sprung mattress at the affordable end of the market.
Guest rooms
With a short one-year guarantee and a modest price, it suits a spare room that sees occasional use rather than nightly wear.
Side sleepers
The reflex foam comfort layer spreads your weight evenly, which means fewer pressure points where you sink in most, typically at the hips and shoulders.
Allergy sufferers
White fibre fillings are hypoallergenic, so anyone prone to allergies gets a lightweight, high-loft layer that still holds its shape over time.
If you share a bed with a restless partner, the interconnected open coil springs transfer movement more than pocket springs do. Across owner reviews, one reviewer felt edge support could be better for sitting on the edge, so it's a slightly weaker choice if you perch there to dress. If you prefer sleeping on a firm mattress, this might not be the best choice.
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 edmonton mattress?
It's listed as medium. That suits most back and side sleepers, although lightweight side sleepers may find any sprung medium a touch firm at first, and dedicated stomach sleepers who prefer a very firm surface may want more support.
Does the highgrove edmonton come with a trial?
Archers Sleep Centre offers a 60 Night Comfort Guarantee, but only if you also buy a Purecare mattress protector. This is the retailer's own offer, not a Highgrove one, so check terms carefully before relying on it.
How deep is the highgrove edmonton mattress?
It's 25cm deep, which means most standard fitted sheets will go on without a struggle. Depth comes from fibre and foam comfort layers sitting over the open coil spring unit.
What guarantee does the highgrove edmonton have?
The retailer lists a 1 year guarantee covering manufacturing faults. That's shorter than many brands offer, which is one trade-off for the low price.
How is the highgrove edmonton delivered?
It arrives vacuum packed, rolled and boxed, so it's easy to manoeuvre through hallways and up stairs. Archers Sleep Centre offers free day-of-choice UK delivery as an online exclusive. Owners say it unpacks easily and fills out quickly.
