Why our sleep experts loved it
Highgrove’s Aspen Memory Pocket 1500 is the sort of mattress that looks, on paper, like it’s been built to win people over quickly. You’ve got pocket springs for structure, a chunky 70mm layer of memory foam for that slow, cushioned hug, and a super soft teddy bear top that’s clearly aimed at comfort first. I should be upfront though. I’ve not had the chance to try this mattress in person, and I also haven’t tested it at home. Archers is in Scotland, so this is a spec-led review based on my industry experience and what the construction typically delivers in real bedrooms.
Design and features
The headline is the combination of 1500 pocket springs and 70mm of memory foam. That’s a generous amount of foam, and in my experience it tends to create a noticeably more “settled in” feel than thinner comfort layers. The pocket springs being small diameter and closely packed suggests a more refined support core, where the mattress can respond in smaller zones rather than feeling like one big pushback layer. In theory, that improves alignment through the hips and shoulders, which is exactly what you want on a medium tension mattress.
The teddy bear top panel is a comfort play, and it’ll appeal to anyone who likes a plush first contact feel. But I’m always a bit sceptical with very soft top fabrics, not because they’re unpleasant, they’re lovely, but because they can be more prone to flattening with time if the quilting underneath is light. The foam encapsulated border is a strong inclusion. It usually makes the edges feel more secure when you sit or sleep near the side, and it can make the usable sleep surface feel bigger.
The breathable venting system is a welcome touch, because memory foam and heat management don’t always get on. Border vents can help shift warm air out of the build, but they won’t magically turn a memory foam mattress into a cool-sleeping one. If you’re a hot sleeper, I’d still go in with realistic expectations and pair it with breathable bedding.
Mattress comfort
If you like that classic memory foam feel, where the mattress softens with body heat and gently moulds around you, Aspen should deliver it. With 70mm of memory foam, I’d expect strong pressure relief through the shoulder and hip, and a calmer feel when you move around at night. That matches the typical “less tossing and turning” promise, and it also lines up with the real customer sentiment we’ve been given. People calling it “very comfortable and brilliant value” is exactly what I’d expect when a mattress nails the basics and doesn’t try to be too clever.
There is a trade-off though. Deep memory foam can feel a little slower to respond, so if you hate that sinking sensation or you want a very buoyant, spring-forward feel, this probably isn’t your mattress. And if your room runs warm, you might notice the foam holding onto heat more than a fresher, fibre based comfort layer would.
Suitability
This medium tension is a strong shout for side sleepers, and that’s where I think it’ll do its best work. Side sleeping needs give at the shoulder, and memory foam tends to excel there. Average weight sleepers should find it comfortable in most positions, and the pocket springs should stop it feeling overly soft or sloppy underneath.
Back sleepers can still enjoy a medium, but I do think some will be better served by a slightly firmer option, especially if they want a touch more “on top” support rather than deeper contouring. And if you’re heavier or you regularly wake with a tired lower back, I’d be cautious. Not because Aspen is poor, but because medium plus deep foam isn’t always the best mix for everyone.
The verdict
From the specs, the Highgrove Aspen Memory Pocket 1500 comes across as a comfort-led mattress that’s been sensibly built, and I like that it hasn’t ignored support. The pocket springs, edge encapsulation, and one-sided easy care design all read like practical choices for everyday homes. The biggest strengths should be pressure relief and a cosy, plush surface feel, and the customer feedback we’ve seen supports that.
The negatives are mostly about expectations. Memory foam can sleep warmer, the teddy top may not look as fresh forever, and medium tension won’t suit every back sleeper long term. But if you want that soft, moulding feel with a stable spring base and you care about value, I’d put this firmly on your shortlist.
