The Sleepeezee Nova 1800 Combination Mattress is a very firm, cooling-leaning pocket spring and memory foam hybrid that prioritises back support and a stable feel over sink-in softness. In store, it comes across as a seriously substantial mattress, the sort that feels built to hold its shape and keep a sleeper on top of the bed, rather than letting them melt into it. That will be exactly what some people are chasing, but it is not a universal crowd-pleaser.
Construction and materials
This is a combination design built around individually wrapped springs paired with a graphite memory foam layer, finished with a "Breeze" cover that claims up to 40% more breathability. The graphite element is there to counter the usual heat build-up associated with memory foam, and the overall build is geared towards pressure relief without sacrificing a firm support base. It is also made in the UK, with the brand positioning it as carefully made rather than mass-produced.
Comfort, firmness and feel
The headline is the feel, it is very firm. In practical terms, that translates to a mattress that resists deep compression and keeps the body lifted, with only a small amount of cushioning from the memory foam at the surface. There is a touch of softness up top, but it reads more as a comfort buffer than a plush layer. This is the kind of firmness that can feel a little uncompromising at first, but the overall sensation is reassuringly supportive and tidy, not board-like for the sake of it.
Support and pressure relief
The pocket springs do the heavy lifting here, giving the mattress its structure and keeping the spine from dipping, especially for back sleepers. The memory foam layer adds a bit of contouring to take the edge off pressure at the contact points, but it does not dominate the experience. The result is a mattress that feels designed for alignment first, comfort second, which is a valid approach when the priority is reducing aches from poor posture overnight.
Motion isolation
Because the springs are individually wrapped and there is a memory foam layer above, movement is noticeably damped compared with traditional open coil mattresses. In store, it feels like the surface settles quickly after weight shifts, which helps limit the knock-on effect of a partner turning over. It is not a dead, foam-only feel, but it is controlled enough to suit couples who are easily disturbed.
Temperature regulation
For a mattress with memory foam, it does a convincing job of avoiding that enclosed, heat-trapping sensation. The breathable cover and graphite memory foam are clearly aiming at hot sleepers, and the pocket spring core naturally allows more airflow than an all-foam block. It still has a slightly warmer touch than a purely spring-led mattress with minimal foam, but it avoids the stuffy feel that puts many people off memory foam in the first place.
Edge support
Edge-to-edge support is one of its strongest practical wins. Sitting and lying near the side feels stable and usable, rather than sloping away. That matters for anyone who uses the full width of the bed, shares with a partner, or simply wants a mattress that feels easier to get in and out of. It feels like a genuinely supportive perimeter rather than a marketing claim.
Practicalities
It comes with a 100 Night Comfort Guarantee, which is important because this level of firmness can take adjustment. The mattress feels notably heavy and substantial, which is reassuring for build quality, but it also means rotating or shifting it is not a one-person job in most homes. The presence of handles is a real advantage here, making day-to-day manoeuvring for sheet changes and maintenance far less annoying than on handle-free designs.
Who it suits
This mattress best suits back sleepers who want a firm, supportive surface that encourages a flatter, more neutral spinal position. It is also a strong option for some stomach sleepers who need extra resistance to stop the hips dropping. It suits couples who want reduced motion transfer but do not want the sluggish, stuck-in-foam feeling. It is also a sensible pick for anyone drawn to memory foam comfort but wary of overheating, as the cooling approach here feels like a genuine design priority.
Who it does not suit
Strict side sleepers are the obvious group to think twice, particularly those with pronounced shoulders and hips or hourglass figures, because the very firm support is less willing to allow the sinkage needed for comfortable alignment. Anyone who equates comfort with plushness, deep cushioning, or that heavy body-hug of classic memory foam will likely find it too upright and too firm. It is also not ideal for those who regularly need to move or rotate a mattress alone, as the weight is a real, everyday consideration.
What customers liked
Feedback consistently leans towards the balance of strong support with enough surface comfort to avoid feeling harsh, with several people noting better sleep quality and fewer aches, particularly around the lower back. Motion isolation is a repeated positive, with couples highlighting that they are less aware of each other moving. Cooling performance also stands out, especially for those who expected the memory foam to run warm but found it noticeably more comfortable than older foam mattresses. Edge support and the usefulness of the handles are also praised as practical, real-world benefits.
What customers disliked
The main drawback is that the mattress can feel very stiff at first, and some people clearly needed a bedding-in period before it reached its best comfort point. The other recurring complaint is simply the weight, it is heavy enough to be a nuisance when changing sheets, rotating, or positioning it on the bed base without help.
Final verdict
The Sleepeezee Nova 1800 Combination Mattress is an excellent choice for shoppers who want a genuinely firm mattress with a calmer, cooler take on memory foam and a noticeably stable edge. In store, it feels robust, supportive, and built with purpose, but it does not try to be all things to all sleepers. It is a strong buy for back sleepers and some stomach sleepers who prioritise alignment and a steadier feel. Side sleepers and anyone chasing a softer, deeper cradle should look elsewhere, because this mattress knows exactly what it is, and it is unapologetically firm.
