Testing team takeaways

To test the Sealy Posturepedic Elevate Sandridge Combination Mattress we have people from our testing team take a closer look at the mattress and form their own opinions. Below is their observations.

I tried this Sealy mattress on the shop floor at a Dreams store, lying on my side and changing position to get a feel for it. As a 66 kg combination sleeper, I noticed the foam cushioning my hips, although my overall impression on my side was more mixed than that detail alone might suggest. The cooling feel was a clearer positive: it felt cool to lie on, and that aspect did not disappoint during my short time trying it in the shop.

What our reviewers found

Pros

  • The Sealy Posturepedic Elevate Sandridge Combination Mattress' firm comfort grade provides solid support, perfectly catering to back and stomach sleepers' needs.
  • The exclusive INFUSE™ Black Diamond Graphite foam layer contributes to maintaining a cool and comfortable sleep environment, ensuring improved temperature consistency.
  • Made with unique AlignSupport® Coil system, this mattress conforms to your body shape for superior support and comfort.
  • Boasting a UniCased® edge support system, the mattress offers enhanced durability and maximum sleeping surface without the risk of rolling off.
  • Endorsed by Allergy UK, the mattress comes with an Exclusive SmarTex® Plus and ProShield® cover, creating a hygienic and allergen-free sleep surface.

Cons

  • Individuals with hourglass figures may find the firm tension uncomfortable due to lack of sufficient sinkage for hips and shoulders.
  • Exclusive to side sleepers, the solid firmness could potentially cause difficulty sleeping comfortably, lacking the necessary contour for shoulder and hip alignment.
  • Despite being a single-sided mattress, it needs regular rotation to maintain its longevity, which could be mildly inconvenient for some users.

Welcome to our in-depth review of the Sealy Posturepedic Elevate Sandridge Combination Mattress. As a ten-year veteran in the mattress industry, I've had the opportunity to test and scrutinise numerous mattresses, including this intriguing one from Sealy. In this detailed review, I'll share my personal feelings and insights gathered from my hands-on experience in the store. I aim to provide you a balanced viewpoint, highlighting its clever features while being candid about areas that might fall short.

Design and Features

Generally, Sealy has a solid reputation in creating premium quality mattresses, and this model is no different. The Sealy Posturepedic Elevate Sandridge Combination Mattress comes with a host of premium features designed to provide both comfort and support. However, it also comes with a hefty price tag, which may deter some customers.

Starting with the design, the first feature that deserves attention is Sealy's new INFUSE™ Black Diamond Graphite foam exclusive to Dreams. Designed to wick away heat and moisture, this layer of foam provides a cooling sensation, which is handy if you tend to get hot during the night. After experiencing the cooling properties firsthand in the store, I am confident that this feature will contribute significantly to your sleeping comfort. The importance of maintaining an optimal temperature while sleeping can't be overstated. An overly warm mattress can disrupt your sleep cycle, lead to perspiration, and aggravate issues like insomnia.1 This makes the INFUSE™ Black Diamond Graphite foam an admirable addition in Sealy's arsenal.

The mattress also features a plant-based INFUSE™ Eco ComfortCore® foam for cushioning the lower back and hips. This offering aligns perfectly with the trend towards eco-friendly options in the mattress industry. However, I am somewhat sceptical about whether this eco-friendly foam genuinely offers superior comfort or whether it's a marketing gimmick.

While the mattress doesn't slack on comfort, it places a great emphasis on support as well. Wielding Sealy's patented AlignSupport® Coils and a UniCased® edge support system, the mattress promises strength, durability, and superior support. While these coils may not have resonated with my personal preference, they truly do provide a firm level of support that some sleepers may appreciate.

Mattress Comfort

Sleeping comfort is highly subjective and can vary from person to person. As for the Sealy Posturepedic Elevate Sandridge Combination Mattress, it has a firm comfort grade. This firmness is fantastic news for back sleepers and some stomach sleepers. However, if you mainly sleep on your side or have an hourglass figure, this mattress might not be suitable for you. There is a lack of sinkage in the support layer of the mattress which side sleepers require for accommodating their hips and shoulders. As such, they may experience discomfort or difficulty in finding a comfortable sleep position.

Suitability

While testing the mattress, it was clear that the back and stomach sleepers would benefit most from the firm mattress. However, it's essential to consider that the firmness of a mattress is a subjective experience and may differ from person to person. Despite not being a great fit for side sleepers, Sealy's patented AlignSupport® Coils might offer them some relief with their contouring abilities.

Another point to mention is the suitability of this mattress for people who sleep hot or live in warmer climates. The INFUSE™ Black Diamond Graphite foam layer does an excellent job at creating a significant cooling effect by drawing away body heat, regulating the sleeper's temperature throughout the night.

What Customers Thought

Owners are pleased with it, and the two words that keep coming up are comfortable and supportive. Several say their backs feel the difference. One review opens "Where has all the backache gone?" and says it disappeared after a month on the mattress. Another owner wrote "my back feels much better using this mattress".

The firm feel suits the people who chose it. One owner called it "Firm but not hard" and another the "Comfiest firm mattress ever". The edges get noticed too. One owner said one of their favourite bits is "the sides that do not sink when you sit on them", and another called it great for people who sleep on the edge because "the edges are well supported". On heat, one owner reported "not overheating".

It took some of them a while to settle in. An owner coming from a full memory foam mattress said "it took a while to get used to the bouncing of the mattress". Another was surprised by how deep the mattress is and needed a few nights before sleeping well on it. The other complaint is smell. An owner found it had "a musty, dusty, no good smell" that kept waking them, and it took about a month of airing for most of it to go.

The Verdict

From a personal standpoint, taking into account my expertise and hands-on experience combined with the product's features and customer feedback, I consider the mattress to offer exceptional quality but at a hefty price. It packs in a bewildering list of features and cutting-edge technology to benefit several sleepers. Side sleepers may find this mattress too firm, and the Eco ComfortCore® foam's effectiveness could be placebo. However, the cooling properties and the firm support it provides might outweigh these negatives for hot sleepers and back sleepers.

Yes, the Sealy Posturepedic Elevate Sandridge Combination Mattress may not put all checks in the box for every type of sleeper, but that should not negate the level of luxury and high-end support that it promises. It's a firm mattress made with the latest technology and premium materials to ensure a cool, comfortable night's sleep with solid support-for those whom it suits.

Sealy has indeed created a technology laden mattress with the Sealy Posturepedic Elevate Sandridge Combination Mattress. However, its hefty price tag and firmness level make it more suitable for a specific subset of buyers. For them, this mattress might indeed elevate their sleep experience to new heights. For others, there might be alternatives that better meet their personal comfort and budget requirements.

  • Side Sleepers
    ★★★★★
    ★★★★★
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers

I have medical issues which causes me a lot of pain . Sleep was very sporadic my old bed was a nightmare to negotiate. I went to Dreams to look at beds . I came away with with an electric bed and mattress which enables me to get in and out of bed with minimal effort sit in bed and read lay with back raised to help alleviate coughing and make breathing easier . The lower section I could raise and it reduced pressure and helped with restless leg syndrome. I must admit I spend more time on my bed than in any other room in the house. I am so pleased I purchased this bed from Dreams . Denise

We went to dreams to try the sleep analyser bed. From it's assessment we tried 4 mattresses. One of which was very good. We ordered and arranged for the old mattress to be disposed of and the new one delivered to the bedroom. The first night's sleep was great, I actually woke up without any aches or pains in my joints. Second night's sleep was even better. A few weeks in and still excellent. Very comfortable and supportive. Would recommend Dreams to anyone. Heck, even the store assistant was great, very knowledgeable and we never felt under pressure to buy.

We got this mattress to replace our full foam mattress. We wanted to move back to a traditional mattress feel and are so pleased we did. This mattress is very firm with superb edge support. At first we thought we had made the wrong decision but after a few nights we adjusted to the feeling and are sleeping better than ever. I know some people love the no springs mattress and whilst it was comfy I just prefer springs. I am happy with this mattress - if you like a firmer feel with a little bit of movement then this is for you.

The bed is very comfortable. No complaints there. I'm new to the UK, so maybe it is knowledge gap, but I wish the instructions would have told me about airing the mattress out. I thought something was wrong with the mattress, as it had a musty, dusty, no good smell that kept waking me up at night. After airing it out for a month, the smell is mostly gone and comfort remains.

Ottoman base is a side opening base, loads of great storage and really well made. Mattress, took a little while to get used to the difference in tension, but now the mattress is very comfy, supportive and given the amount of decorating I have been doing, I am waking up in less pain and achey than I would usually have done, I'm crediting this to the mattress.

After trying about 10 different mattresses we finally settled on this one. I suffer from Spinal issues and my husband has hip and knee problems, and this mattress has been the best for both of us. I have to say the service we got and the time we spent in the store was wonderful. Highly recommend this mattress

Where has all the backache gone? It disappeared after one month of sleeping on our new mattress. Frequent tossing and turnng is a thing of the past too. Solid and supportive the mattress provides an excellent night's sleep. We find that the outstanding build quality gives a new era of comfort.

I thought our previous bed was comfortable but this is on another level! Waking up after a truly restful sleep feels incredible. This is a firm mattress but does not feel hard at all. I would say this offers the perfect level of support and comfort. I honestly can't recommend enough!

We were unsure about purchasing a pillow top mattress but I have to say it was one of the best decisions we have made. The mattress is exactly how we like it and is superbly made. I can see us using Sealy again based on how good this mattress is.

Really very happy with this mattress, firm but comfortable and from night 1 I've had the best nights sleep I've had in years! Laying on this feels like your whole body is being supported which is ideal for those aches and pains. Very happy.

A lovely bed chosen via the mattress analyser in store. Exactly what we needed, although it surprised us with just how deep the matress was. For a few nights it felt like 'the Princess and the Pea' - but now we're used to it and sleep well.

One of my favourite bits about this bed is the sides that do not sink when you sit on them. The bed is super comfy, and was a great choice. We tried it in the store but bought online - would recommend trying for sure!
