In our experience, the materials and construction that go into this product can make it suitable for the following people.
Fairly reasonable price point despite the premium nature of the components.
Gel foam has many of the benefits of traditional memory foam but with the benefits of better breathability.
Pocket springs are a personal favourite and offer great body contouring.
New models and so reviews will be somewhat limited.
No European sizing available.
Price point may still alienate those on a budget.
The Sealy Blakemere Geltex Enhance 1000 Pocket Mattress is built to feel inviting the second you get into it, with a quilted pillow top and a layer of Geltex foam over the springs, and owners call it comfortable: one says they 'generally wake up with no aches or discomfort' and another wrote 'We sleep like logs'. With 1000 individual pocket springs, the product gives you good levels of support that outperform open coil and reflex foam alternatives. Each of those springs sits in its own cloth pocket and reacts on its own, with a second layer of 800 mini pocket springs above them, so I'd expect the surface to move in smaller sections rather than dipping as a whole, which is what you want if you share the bed. the result is a base layer that offers contouring to your body shape and provides extra comfort. When it comes to the top layer you have a Geltex layer of gel foam that combines with the springs for a softer feel, and because Geltex is an elastic foam that springs back I'd expect it to cushion your back without that stuck-in-the-mud memory foam vibe, making it ideal for combination sleepers of average BMI. Owners who came from firmer beds notice the softness: one who had always had a firm mattress says it 'Felt very soft at first' and needed a week or so to adjust. A side sleeper who calls himself a 'heavy bloke' tried the firm equivalent first, 'just didn't find it comfy' and says this is 'much better', but if you're lighter (say under 70kg) that medium tension could still feel a bit firm around the shoulder. This is an ideal choice for most as that medium tension has mass suitability at its heart. Thanks to the pocket spring base layer, the product also benefits from strong Edge to Edge support, and I'd expect that spring unit to stop the side folding under you when you perch on it to put your socks on, even with a soft pillow top above it, meaning you can make use of the full width of the mattress. That said, pillow tops can feel a touch bouncy and less 'flat' than a tighter-topped mattress, so if you like a really firm, stable surface this might not be your thing. The result of all of this is that the Sealy Blakemere Geltex Enhance 1000 Pocket Mattress is a strong choice for anyone looking for a supportive and comfortable mattress for a great night's sleep, as long as you're happy with a medium feel rather than something properly firm.
The pocket spring base is the durable part; the pillow top above it is the bit that softens first, because that's what pillow tops do. The guarantee is decent, but it isn't the longest you'll see at this price point, and I'd personally want longer if I'm buying for the long haul.

Common questions answered by our team first, then questions shoppers asked the retailer, with the retailer’s own answers.
We've expanded on the specifications of the product to better help you understand its benefits.
Pocket springs are a type of mattress that uses individual springs that are each encased in their own fabric pocket. These springs are then attached to the mattress fabric, creating a supportive and comfortable sleeping surface. Pocket springs are often considered to be a step up from traditional coil springs, as they provide a more targeted level of support.
Geltex is unique to Silentnight and Sealy, offering many of the same benefits as memory foam from a comfort perspective but without the downsides of heat build up and retention. The result is a supremely comfortable layer that keeps you at the right temperature, allowing you to sleep deeper and for longer.
A mattress that is breathable allows air to circulate through it, keeping you cool and comfortable as you sleep. Many mattresses are made with materials that trap heat, causing you to wake up hot and sweaty. A breathable mattress helps you stay cooler and can promote a deeper, more restful sleep.
Soft medium tension provides a balance between firmness and plushness. For side sleepers, this means that it can adequately support your body's weight while allowing your hips and shoulders to sink in slightly. This helps maintain proper spinal alignment, reducing pressure points and discomfort.
The cosy quilted pillow top design adds an extra layer of softness, providing a plush surface that promotes comfort during sleep. It enhances the overall feel of luxury and can aid in reducing pressure points by adding additional cushioning on the mattress surface.
Meets BS7177: 2008 for domestic low hazard use. Testing covers resistance to a smouldering cigarette and a small flame the size of a match flame, not suitability for hotels or care homes.
Marketed as 100% recyclable at its life's end. Check local collection and recycling options, because a service may not accept the whole mattress even if its materials are recyclable.
Medium marks the centre of the firmness scale. Use this brand's range when comparing options, since manufacturers set their own ratings and share no universal firmness standard.
Fabric pockets surround individual springs, allowing each to move under pressure without pulling directly on its neighbours. These form the support system, per the listing.
Billed as spreading pressure across the sleeping surface. Shoulders and hips are the named contact points, though the feel will depend on your build and sleeping position.
UK handcrafting is the maker's own claim, while National Bed Federation approval is a membership scheme auditing fire safety, clean fillings and honest labelling.
1000 individually pocketed springs flex separately under load, forming what Sealy calls an 'unstoppable' support system with a local response to pressure.
Made in the UK gives the country it was built in and little about quality on its own, so judge the materials, construction and guarantee separately.
Comfort layers are claimed to let shoulders and hips sink in and spread weight, with suitability depending on body weight and sleeping position.
A padded pillow top beneath a knitted cover is advertised as softer, while its single sleeping side requires rotation without turning.
Allow for 27cm of thickness, about 10.6 inches, when selecting fitted sheets and calculating sleeping height above the base.
The sleeping layers are arranged for use on one face, so turning the mattress upside down is not part of its care routine.
Four vertical handles offer handholds when turning or repositioning the mattress, which can otherwise be awkward to grip.
A five year guarantee comes with it. Check the retailer's terms for the fault criteria and for how to make a claim.
A pillow top adds an extra padded layer sewn onto the sleeping surface.
Five years of guarantee cover come with it.
