Pros & Cons

Here we collect tests, guides and product reviews so that you can create a picture of what others think about the product. This analysis and review is based on my experience and a decade of industry insight.

Geltex is a great comfort layer that works really well, unique to Sealy and Silentnight, this breathable layer is preferable over memory foam for us.

Reasonable price point, although Sealy are trying to break back into the mid-high end, removing their budget line-up.

Strong customer reviews show the mattress performs well.

Pillow tops are contentious, I don't personally have a problem with them however some find them extra layer a hinderance rather than a help.

Price points are going up from Sealy making it harder to access that unique Geltex layer than. in previous years.

Why our sleep experts loved it

Welcome to the world of comfort and support with the Sealy Alston Gel Advantage Pillow Top Mattress. This product claims to allow you to experience a level of comfort that you never thought possible. This innovative mattress is designed to provide the perfect balance between comfort and support. It features a combination of PostureTech Core Support Springs and Geltex foam that provides the ideal level of support for all body types and sleeping positions. But does it live up to the hype? Let’s find out below.

The Sealy Alston Gel Advantage Pillow Top Mattress is an all-around high-performance mattress that is designed to offer a perfect balance of comfort and support, offering better breathability than the competition at a price point which sits fairly well in the middle-ground. It is designed with a combination of PostureTech Core Support Springs and Geltex foam that work together to provide excellent comfort and support. The Core Support Springs are uniquely designed and unique to Sealy and move somewhat independently of each other, resulting in better motion isolation and pressure relief than some of the competitors in this space. The Geltex foam is designed to provide a plush and luxurious sleeping surface that contours to your body for good comfort and support, rivalling memory foam for comfort but with better breathability and cooling properties.

Benefits of PostureTech Core Support Spring

PostureTech Core Support Spring mattresses are one of the most popular mattress types on the market today despite being limited to Sealy products only. This is due to the fact that they are surprisingly durable, long-lasting, and tend to provide a good level of support for a reasonable price point. This means that you won't be disturbed if your partner moves around in the night.

The Core Support also provides superior edge support, which helps to reduce sagging and provides a more consistent sleeping surface. Finally, the PostureTech Core Support Springs are also designed to provide better ventilation and temperature regulation, which helps to keep you cool and comfortable throughout the night.

Benefits of Geltex Foam

Geltex foam mattresses are one of the most popular mattress types on the market today. This is due to the fact that they are incredibly comfortable and provide superior support. The Geltex foam is designed to contour to your body for superior comfort and support. It also provides better breathability and cooling technology which prevents you from getting too warm while you sleep, performing better than memory foam in this regard. Ultimately, Geltex foam provides superior ventilation and temperature regulation, which helps to keep you cool and comfortable throughout the night.

Customer Reviews

The Sealy Alston Gel Advantage Pillow Top Mattress has received overwhelmingly positive reviews from customers with many customers have commented on the great balance of the medium tension, proving to be suitable for both side and back sleepers. Others commented on the superior comfort and support that the mattress provides over their previous product. Negative reviews are a bit harder to come across with the only real complaints being around the delivery process and the lack of turning handles. The lack of handles is a bit of a pain and a bit of miss-step from Sealy although it might not affect everyone equally.

Suitability

*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
    ★★★★★
    ★★★★★
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • 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
    ★★★★★
    ★★★★★
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.

Performance

  • Breathability
    ★★★★★
    ★★★★★
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress
    ★★★★★
    ★★★★★
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability
    ★★★★★
    ★★★★★
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Odour

  • Initial Odour
    ★★★★★
    ★★★★★
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
    ★★★★★
    ★★★★★
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

Brand Rating

  • Overall Brand Rating
    ★★★★★
    ★★★★★
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

Took a long time choosing a mattress as i didn't realise there were so many to choose from, went for a Sealy make as they had some good reviews, then decided i would go for memory foam and springs, and then how much to pay for one. Choose this one in the end and so pleased i did it's lovely to sleep on although firm it's not rock hard. Would by again.

So comfortable and supportive, never had a memory foam mattress before and it's a revalation. Feels really luxurious and just the right firmness. Bit like a hotel bed. Struggling to get to work now as I don't want to get out of bed :)

It's on the firmer side and supports the body very comfortably. The material is very soft and the mattress is quite deep so good if you have a bed low to the ground and want a little more height.

Perfect mattress, firm but not like the floor, getting lots of support where I need it, hips, lower back. As a bonus it's lovely and comfortable too.
