The search for the perfect mattress can sometimes feel like looking for a needle in a haystack. There are countless options on the market, each with their own unique features and benefits, which can make it difficult to sift through the clutter and find the mattress that's truly right for you. However, during our diligent search for excellence in slumber comfort, we came across the Horizon Eclipse 3000 Pocket Memory Mattress, a top-rated pick for 2025 offered by Mattress Online. It's a pocket-sprung hybrid with a layer of Bamboo memory foam on top and a medium-firm rating, which is the kind of all-rounder we'd steer most people towards when they aren't sure what they want.
How we assessed it
Two layers of pocket springs under memory foam should suit couples. Each spring sits in its own fabric pocket and the foam on top absorbs movement, so a partner turning over shouldn't disturb your side of the bed. The memory foam should mould around your hips and shoulders and take pressure off them, which fits what owners report: one who was sceptical about memory foam called it "THE most comfortable mattress EVER" and said they had "no aches and pains". Don't read medium-firm as hard, though, because one owner found theirs too soft. Memory foam holds warmth, so we'd expect this to sleep warmer than a sprung mattress with no foam in it.
Design and Features
At the heart of the Horizon Eclipse 3000 is a smartly-engineered spring structure, combining 2000 pocket springs and an additional layer of 1000 mini springs. These individual pocket springs designed to align your spine optimally while providing you with comfort and targeted pressure-point relief. We were impressed by the inclusion of a layer of sumptuously soft Bamboo memory foam, which offers a comforting sleep surface that adapts to your body contours.
The mattress has a medium-firm tension, striking a balance between plushness and support, expected to accommodate different sleeping positions adequately. It's encased in a sturdy foam border which not only aids in edge support, but also in limiting excessive sagging over time. A depth of 27 cm and a removable quilted memory foam cover, which can be dry-cleaned, attribute practicality to the design.
Certainly, the Horizon Eclipse has admirable features, but our experts were a little sceptical about the actual cooling efficiency of the Bamboo cover. Memory foam is known for trapping heat, and while the bamboo element is a thoughtful addition, its real benefits in maintaining a cool sleep environment is up for debate.
Mattress Comfort
The Horizon Eclipse 3000 positions itself as a medium-firm mattress, meaning it strikes a balance between plush comfort and solid, reliable support. On paper the memory foam and soft fibre should give first, with the pocket springs firming up underneath as your weight goes on.
Owners mostly agree that it's comfortable, though the feel doesn't suit everyone.
Suitability
The Horizon Eclipse 3000's medium firmness is apt for both side and back sleepers of average weight. The mattress's support and conforming ability should comfortably cushion a side sleeper's shoulders and hips, while providing a back sleeper the necessary spinal support. However, side sleepers with an hourglass figure might need to consider a slightly softer model to ensure comfortable sinkage.
The 3000 pocket springs combined with a layer of adaptable memory foam suggest that this mattress could be a favourable choice for individuals suffering from joint pain or back discomfort. The potential for motion isolation further makes the mattress a feasible choice for couples.
What Customers Thought
Owners mostly say it's comfortable. One wrote: "I sleep right through and no night sweats either !" Another bought it for their mum, who has arthritis, and said it "made it so she sleeps through the night". Several owners also praise the value, and the service gets mentions for knowledgeable showroom staff and prompt delivery.
Not everyone gets on with it. One owner found it too soft and wrote "Another marshmallow! Really annoyed.", and another said "The edges are not square so you tend to roll to the edge." One owner who likes it said it took a few weeks to adjust to the new mattress.
The Verdict
The Horizon Eclipse 3000 Pocket Memory Mattress certainly presents a compelling case, armed with its clever micro-spring design, Bamboo memory foam layer, optimum spinal alignment, and sturdy edge support. Most owners are happy with it.
The memory foam layer does add a sufficient level of plushness to the feel of the mattress, but questions about its heating properties remain. For warmer sleepers, this could be a potential point of concern.
Overall, with a 5-year guarantee and comparatively lower price point in the high-spec market, the Horizon Eclipse 3000 seems to offer a fair balance of value, comfortable sleep experience, and durable quality. It ensures restful sleep, suiting the needs of most sleeping positions, with the potential to alleviate long-standing discomforts. Provided the warmth of memory foam doesn't deter you, we'd suggest the Horizon Eclipse 3000 is a worthy contender to consider in the pursuit of your perfect mattress.
