What Makes The Sealy Activsleep Ortho Posture Pillow Top Mattress Great?


This product is unlikely to cause any sort of allergic reaction. Ideal if you suffer from any sort of allergy problems

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

5 year guarantee

A 5 year guarantee is quite rare in the industry and is a great indicator of the retailer beleiving in their product. Anything go wrong in the next 5 years, no drama, get it replaced.

Handcrafted in the UK

Handcrafted in the UK means that the product is built here, by people being paid a fair and honest wage using certified and safe products of good quality and construction. UK manufacturing is some of th best in the world and all of that is reflected in this product

Orthopaedic Support

Do you suffer from back pain? If so you will likely find that an orthopaedic mattress will be massively beneficial to you. Slightly firmer in the comfort side of things but ultimately with a better support layer means that your back and neck will thank you for years to come.

Medium to Firm

Firmer than the average mattress, a medium to firm mattress is ideally suited to those that are looking for extra back support but still require and amount of comfort from their mattress. Ideally suited for a large range of the populus and becoming much more common, deviating away from the previous medium-for-everyone model.

Pillow Top

Many mattresses that you see that look really plush, do so because they feature a pillow top. Benefits of a pillow top mattress are increased comfort and luxury styling. Downsides are they can be a bit of a pain to get sheets over properly

Knitted Cover

It is common in the industry to have a knitted cover, these covers can come in a variety of patterns but are typically hard wearing and do not present problems for consumers.

Featuring high levels of orthopaedic support, to care for your back

Responsive firmness, getting firmer as more pressure is applied

Sealy's PostureTech Core Support spring system provides and a firmer feel where you need it most

Luxurious pillow top for enhanced comfort

Medium-firm support for the best of both worlds

A medium firm tension mattress is slightly firmer than your average medium mattress. This is ideal for those who either prefer a little bit more support, or, those that have a slightly higher BMI than average. You may also benefit from a medium firmness mattress where you are suffering from neck/back pain as the additional support can help prevent and alleviate these symptoms.

Sleep cooler and fresher, thanks to Adaptive technology

Adaptive helps reduce moisture and heat build-up, to prevent overheating as you sleep

Purotex probiotics help fight against dust mites and bacteria

Hypoallergenic - a great choice if you suffer from allergies

Beautifully designed knitted cover, micro-quilted to lock in the fillings

This mattress comes with a quilted cover. Many people overlook the cover as a need for consideration however, the right cover can add additional comfort and in the case of this one here, adds quilted comfort that offers a soft but hard-wearing cover that is both breathable and stylish.

No need to turn over - simply rotate to keep it in great condition

Rotating the mattress remains an important step in maintenance. The comfort and support layers of a mattress settle over time and it is necessary to rotate at certain periods to help reduce risk of dipping while you sleep in the same patterns and locations across the mattress.

Soft white fibres

White fibres tend to be a mixture of polester and other non-descript synthetic fibres

26cm deep

26CM is a deep mattress. This sort of mattress may require a slightly deeper fitted sheet to avoid it constantly popping off. That aside, 26CM is above the industry average in terms of depth and while not necesserily a guarantee of quality, you cannot get comfort and quality from a thin mattress


Single sided means only one side is comfy. Positives are you only need to rotate the mattress occassionaly rather than the more cumbersome rotate and flip. Downside is the lifespan of the product may suffer as a result, only marginal, but worth mentioning.

Approved by the National Bed Federation

The NBF is one of the most prestigious awarding federations in the industry, helped slightly by the fact that it is one of the only, however, it is still a great source of comfort knowing that this product holds approval by the team

Depth: 26cm

The industry standard for mattress depth is 7 inches. With most offering a comfortable 10 to 14 inches, so this one at just under 10 inches is one of the most popular sizes. The higher the load, the deeper it needs to be but a quality mattress in this size can be equally as comfortable and supportive as a deeper budget mattress. 

Approved by Allergy UK

If you have allergies then you may want to consider a mattress like this. Approved by Allergy UK, this product has fillings that are approved for those that suffer from a host of common allergies and while there is no guarantee that this product will prevent allergies, it should prevent further problems for those that do suffer

Fire Resistant

Fire resistant does not mean the product will never catch fire, rather, it will not go up in flames quite so quickly. Resistant to fire in the same way that I am resistant to kisses, sooner or later you end up giving in.

PostureTech Core Support Springs

Providing even weight distribution, the PostureTech spring system feels soft then gradually gets firmer as pressure is applied. The entire spring unit is twice tempered, making it strong. Their Smaller diameter means they can fit more into an area, allowing for a more fine-tuned level of support.

Changed my soft mattress to this Sealy, needed a firmer one to help support an annoying lower back pain. So far so good, I wanted it firm but not like a plank, the pillow top adds an additional comfort layer that seems to make it firm but comfortable.Definitely a good buy, Im not cured yet but its certainly improved and Im sure Im sleeping better!


Love this pillow top mattress, had a Sealy previous but this is luxury and quality, the newness smell soon wore off, I would recommend this mattress, also excellent service and delivery from Mattress on line, I have had mattresses before from this company and no complaints, thank you .


Amazingly supportive mattress, really happy with my purchase, its firm but not overly so. If, like me you are looking for an orthopedic mattress but dont want to sleep on a board I can recommend this Sealy one.As a bonus the pillow-top adds a lovely feeling of luxury and opulence.


I bought this mattress to help with pain I have due to a broken femur, back pain and arthritis and boy does it work!I have reduced the amount of painkillers I take. But best of all I get a good nights sleep.
