Becky's Thoughts On The Sealy Posturetech Superior Mattress

The Sealy Posturetech Superior Mattress is one of the latest in the Sealy range exclusive to Dreams. It has zonal support thanks to it's traditional spring support system, this helps ensure that the spine remains aligned due to the "push back" nature of the firm traditional layer.

This mattress also features what Sealy have dubbed, an Edge Guard, this is just fancy edge to edge support that gives you full usage of the entire spread of the mattress without fear of dips of divots as you navigate your sleep throughout the night,

When it comes to the comfort layer, this comes in the form of the latex filling, a resilient and body moulding layer that is both natural and possessing many of the positive points of memory foam with little of the downsides. 

Finally the mattress comes with a luxurious pillow top to further aid comfort above the latex layer. This utilises Sealy Smart Fibres that have been endorsed by Allergy UK to reduce the allergens in the bedroom, working hand in hand with the other layers to produce a comfy, safe and luxurious mattress for all.


What Makes The Sealy Posturetech Superior Mattress Great?

Rotate Regularly - Rotate head to toe weekly for the first three months, then every month thereafter

Your mattress should be rotated on a regular basis as this is the easiest way to prolong and increase the longevity of your mattress. The main benefits to regularly rotating your mattress is the continued support and comfort while reducing any risk of sagging that may otherwise occur


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

Comfort Grade - Medium

A Medium firmness mattress is the most common build offered due to the range of suitability offered in such a mattress. This type of mattress will be better suited toward averagely weighted people, while lighter people should opt for a medium-light, and heavier people considering a medium-firm.

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.

Sumptuous pillow top

With a pillow top, this mattress effectively comes with it's own built-in protector. That's all a pillow top really is, an additional top layer of comfort which makes all the difference when it comes to getting that good nights sleep. We quite like pillow tops, they have their place in the industry. 

Posturetech spring mattress

Exclusively to Sealy, the posturetech range offers enhanced comfort and support using their patented spring system

Latex fillings

Latex is a luxurious material of natural origins and is one of the better materials for mattress construction due to it's softness, breathability and resilience. You will find latex often used as a top comfort layer and occasionally used as a core/base layer due to it's additional supportive properties.

Smart Fibres

The smart fibre comfort layers sit at the top of the mattress above the springs or reflex foam (depending on model) and offer a breathable layer to help regulate temperature throughout the product and keep you cool while you sleep.

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

Customer Reviews For The Sealy Posturetech Superior Mattress

Based on 16 review

So good we reordered!

We bought this mattress about 2 weeks ago and already we are bedded (!) in and so pleased with our purchase. We actually bought this mattress in super king size 3 years ago but due to moving house we have had to replace our bed with a king size instead and had no hesitation in ordering the same mattress as it’s just sooo comfy. We ordered a sealy mattress as after staying in a hotel and sleeping on a sealy mattress we just had to! Great buy.. great value and a great kip! Will probably order again if they are still making them in a few years!


Don't go for the Mattress protector option

We got this bed about 3 weeks ago. The first 2 weeks, the bed was too hot, and rustled every time you moved. We realised the plastic mattress protector we were given for the extra warranty was the problem; a cheap plastic sheet that didn't fit the bed properly, and was like the one's you give to 2 year olds in case they wet the bed!!! We have changed this now, I guess this will invalidate the warranty, but the bed is great now. We took the Super King Size with Ottoman option which is really useful.


Bouncy and hot

We bought this a month ago but have struggled to get on with its bouncy, springy firm mattress. I can feel my husbands every move and the latex topper can be too hot . I'm looking forward to changing this to a natural material bed which doesn't hurt my joints. Husband loves it as it strangely keeps him cool and is firm enough for his weight. Real shame as I could do without the hassle!


Perfect nights sleep

This mattress is incredibly comfortable. It doesn’t sink like other mattresses and has exactly the right amount of firmness to support the body without feeling like a board.


Brilliant service and products

We recently bought 3 beds and a mattress and we are very pleased with them. We have had lots of good comments about out new beds.



Very pleased with my new Mattress/Bed. It is so comfortable and seems to keep you at a good body temperature. Highly recommend.


Super comfy!!

I’ve had this mattress about 5 weeks, and I love it, it really is so comfy! Impressed


Quality, comfort, support & durability

The mattress to me seemed to have everything I wanted and I wasn’t disappointed
