About the Sleepeezee Zenith 4500 Combination Mattress
Last checked
A 4500 combination build is the important detail here, because the number is doing more than describing one plain pocket-spring unit: the Zenith pairs responsive pocket springs with a micro-sprung, pillow-top comfort section, then adds two layers of graphite-infused memory foam above the support core. The tension is medium, 3 of 5. That places it in the middle of the comfort scale, but the construction pushes the first feel towards cushioned pressure relief rather than a flat, traditional pocket-sprung surface. The spec is generous in one respect: micro springs plus a double memory-foam layer is more elaborate than simpler memory-foam hybrids, which often rely on a single foam slab over springs. The practical limit is that graphite does not turn memory foam into wool, cotton or latex; it is still a close-contact comfort material, just one designed to shed heat better than standard visco foam. The Breeze 3D cover and edge-to-edge support also matter day to day, as they target two common hybrid complaints: warmth through the top layers and softness around the perimeter. It remains a plush mattress rather than a stripped-back orthopaedic build.
Side sleeping is where this mix reads most comfortably: the medium feel, pillow top and memory foam give shoulders and hips somewhere to settle, while the spring base stops the whole mattress feeling loose. Average-weight back sleepers are also in range, especially those who like some cushioning under the lower back, though a firmer pocket-sprung mattress may suit anyone who wants a flatter, more braced feel through the pelvis. Comfort and reduced partner disturbance come through strongly in repeat feedback, with the foam and pocketed spring layout matching the repeated praise for less jiggling when someone turns over. Edge support is also described positively, which fits the reinforced perimeter claim and helps couples use more of the sleep surface. Heat feedback is more mixed than the cooling language suggests: several experiences mention a cooler, fresher night, but one critical buyer found the foam layer too warm, especially once a mattress protector was added. The bulk is the more repeated nuisance, with deep construction causing fitted-sheet struggles and the mattress feeling large to handle. It lands well for average-weight side sleepers and couples wanting cushioned comfort with steadier edges; very hot sleepers, or anyone set on standard-depth bedding, may prefer to consider a natural-fibre pocket-sprung mattress or a firmer, less foam-heavy hybrid.

Ive been sleeping on this SZ mattress for a couple of weeks now and its pleasantly comfy without feeling like youre sinking into treacle. Its got a nice cushioned top and Im not getting jiggled about when my other half turns over, which is a small miracle at my age. It also seems to stay fairly cool through the night, and the edges feel sturdy when you sit on the side to put your socks on. Only thing is its quite a deep one, so my old fitted sheets have been having a bit of a struggle.
I expected a quality mattress from Sleepeezee because of their Royal Warrant, but the Zenith blew me away. What I noticed most when sleeping on it is the motion isolation; the memory foam holds you perfectly in place, so you don't even know your sleep partner's there! It's got great support right the way up to the edge, so you never feel as though you're going to slip off. I wasnt sure about the cooling elements of the mattress, but as a warm sleeper, Ive noticed its improved how quickly I fall asleep and how often I wake up in the night. I love that it's crafted in the UK and I also love how deep the mattress is – youll definitely need an extra deep fitted sheet! Overall the quality and support exceeded all my expectations.
Absolutely love this mattress! Super comfortable with the perfect balance of support and softness. Im sleeping better and it feels high-quality and well made. Highly recommend!
I thought I knew comfort, but then I got this mattress and realised what comfort was. Its supportive yet super comfortable. The fillings and set up set this mattress apart from the rest and I would highly recommend it. SO GOOD!
Having the best sleep for a long while, no aches and pains. it is quite bulky.
This mattress offers luxurious comfort and supportive, Handcrafted in Kent for Dreams, it features 4500 pocket springs that adjust to your body, providing personalized support and reducing movement. The medium comfort grade offers adaptive support, making it suitable for many sleepers. The Breeze cover keeps you cool with its breathable design, and the double layer of graphite memory foam prevents overheating. The plush pillow top, combined with micro springs, adds extra softness and luxury. Edge-to-edge support ensures you won't feel like you're rolling off the bed. Plus, it's recognized for its quality with the Royal Warrant from HM The King. This mattress combines modern technology with traditional craftsmanship for a restful and luxurious sleep.
This mattress has an excellent build quality, but I personally find that the foam layer on the top of the mattress makes me overheat in bed, also if you add a mattress protector water proof or ordinary cotton, it makes the overheating situation a lot worse, to the point where one cannot sleep with a mattress protector in place, so not for everyone.
Purchased the mattress for my younger daughter. She loves it. It is super comfy and the quality is superb. Cant fault it. Have ordered a king size for myself just waiting for delivery. The price of the mattress was reasonable as I got it on offer 20% off.
Really great mattress and offers excellent support. we both have a much better sleep now and the pillowtop offers even more support and additional comfort compared to a standard mattress that does not come with a pillowtop. absolute gamechanger!
Really nice mattress, we went from a 9 year old soft/medium Flaxby mattress that has seen better days, to the Sleepeezee Zenith 4500 Combination mattress. We absolutely love it. It is a solid mattress but the memory foam feels supportive and very comfy. I have a lower back injury and this mattress has honestly been amazing for me. We're converts to Sleepeezee!
