About the Sealy Posturepedic Elevate Gladesville Combination Mattress
Last checked
AlignSupport coils and plant-based INFUSE Eco ComfortCore foam make this a coil-and-foam combination mattress rather than a soft, sink-in foam bed. This is a firm, 5 of 5, support-led build. The useful spec call is that Sealy is chasing posture control through a responsive spring unit, firmer tension and perimeter casing, not through the deep contouring found in softer memory-foam hybrids; that is credible for back support, but conservative for pressure relief at the shoulder and hip. EternityFibre adds a softer surface layer, so the top should not feel like bare springs, while the SmarTex Plus and ProShield cover is the more unusual part of the package for this tier: cooling and allergen-protection claims are common, but Allergy UK endorsement gives the cover more substance than a generic “fresh feel” finish. UniCased edges are also meaningful in real bedrooms, because a firm mattress with reinforced sides should feel usable closer to the border, especially for couples or anyone sitting on the edge to dress. It is single-sided, so maintenance is rotation rather than flipping, which is convenient but puts more responsibility on regular turning from head to foot.
Back sleepers are the natural audience here, especially those who dislike dipping through the middle of an older mattress and want a flatter, more braced surface. Fit comes before plushness here. Praise repeatedly centres on firmer support, improved sleep quality and less morning discomfort, with one heavier sleeper describing the mattress as having the backbone they needed; that matches the firmer coil system and edge casing rather than contradicting the spec. Motion transfer also comes through well in the stronger feedback, with shared-bed disturbance described as low, although the side-sleeper praise in the sample is thinner and should be treated cautiously because the firmness still gives hips and shoulders less room to sink. A recurring product fault does not emerge from the supplied feedback, so the main reservation is suitability: curvier side sleepers, lighter bodies and anyone who relies on cushioning around the shoulder may find the same firmness that helps back sleepers becomes too blunt. The temperature story is sensible rather than miraculous, with breathable cover materials and fibre comfort layers likely to feel fresher than dense all-foam builds, though hot sleepers who need active cooling may need a more specialist cooling hybrid. The Gladesville lands well for back sleepers, front sleepers who like a braced surface, and couples wanting firm edges; side sleepers chasing deep pressure relief should aim for a medium-firm pillow-top hybrid or a softer pocket-sprung comfort build.

After a few nights on this very firm mattress, my back feels nicely supported and Im not waking up in a grump. Its properly sturdy round the edges too, so I dont feel like Im about to slide off when I perch there to put my socks on. The top has a softer touch than I expected, and it doesnt seem to get overly warm. Not cheap, but it feels like one of those purchases youll be quietly pleased with.
Finding the right balance of comfort and support can be tricky, but this mattress does a pretty good job. I've noticed a significant improvement in my sleep quality since using it, particularly on weekends when I get to sleep in a bit, smooth sailing so far.
This mattress is the epitome of comfort and support, and I couldn't be more thrilled with my purchase. The very firm comfort grade is perfect for those who need robust support. I wake up feeling rejuvenated and free from any discomfort. The EternityFibre™ at the top of the mattress adds a sumptuous layer of comfort that feels like being cradled in luxury every night. Knowing that this mattress is handmade in the UK adds a touch of craftsmanship and quality that is truly unmatched. This mattress has revolutionized my sleep experience. If you're looking for a mattress that combines luxury, support, and eco-friendly materials, the Premium Sealy Posturepedic is the one for you.
Oh my gosh!!! Amazing mattress. I was u sure at first not understanding the concept of the spring system, the more pressure applied the firmer it gets!!! No disturbance from sharing the mattress either. Nice firm edges. This mattress is a big beautiful beats of a products. Looks great, padded nicely and just so supportive. I cannot scream loud enough about this product. No noise from the spring system, no pinging sounds or metal on metal sounds, it is silent, big and beautiful. I cannot convey how happy i am with this mattress and being 20 stone I needed something with a back bone. Sealy.... I love you!!!!
I had waited for about a decade before replacing my matress - after the first night I wished I'd done it sooner. No more squidgy valleys, but a lovely firm bed restored. Delivery was super-efficient, and having the old one taken away for recycling was a load off my mind. Great service, and perhaps surprisingly the best value for money too!
This is really good product (sealy posturepedic mattress ) and it is the best mattress we ever had. Good sleep is one of the most valuable part of my life and with this mattress I can feel the appreciation to my good sleep…. Thank you dreams for supplying my dream mattress …..
Super firm and comfy perfect for those who suffer with back ache as I can say it has helped mine tremendously
I thought our previous mattress was comfortable, but this one is on another level! Waking up after a truly restful sleep feels incredible. Im so pleased with this choice and honestly cant recommend it enough!my entire experience with dreams has been flawless. Im so pleased with this choice and honestly cant recommend it enough! If you are on the fence, take the leap—you won't regret it!
Honestly such a firm and supportive mattress . Best purchase I've made in a bed for a long time .
Ive been sleeping on this mattress for a few weeks now, so I feel confident giving a well-rounded overview. The build quality is exceptional — its clearly well made, with a smooth, silky finish that feels premium from the moment you lie down. The mattress is firm but not overly so. I suffer from lower back pain and have tried many mattresses over the years; some help, some dont. With this one, Ive yet to wake up with any aches or discomfort, which is a huge relief. I tend to sleep on my back while my partner is a side sleeper, and it has supported both of us equally well. Another big plus is the lack of motion transfer — neither of us feels the other move during the night. Overall, weve both enjoyed consistently great nights sleep.
The Gladesville mattress has been super comfortable and transformative for my sleep. This mattress offers more support that the mattress it replaced and has been a great change for my sleep.
The mattress is very comfortable, firm, great for back support and also edge support. Sleeping on a great mattress has really improved our sleep quality. The service was quick and simple, and setup in no time, so I'd also recommend this Dreams service.
