Sealy Blackwell Traditional Spring Mattress Review

The Sealy Blackwell Mattress has a base layer constructed of open coil/traditional spring known as PostureTech Core Support. This is a great budget option that helps keep prices low while still offering sufficient body contouring and support. 

The base spring unit comes in a firmer tension, allowing you to get sufficient support throughout the mattress making it an ideal choice for those that are looking for a firm feel be it from preference or to help those with back or neck pain.

From an outward and design perspective, the Sealy Blackwell Traditional Spring Mattress is hard tufted for a luxury feel with enhanced edge support preventing roll-together and roll-off.

For those that don't know, Sealy is one of the biggest retailers in the industry and is particularly favourable in many national outlets as an alternative to their sister-company, Silentnight.

I really like the price point for this mattress and the existing reviews you find below all seem to agree, you get a lot of value for your money and while this mattress does not do anything particularly new or exciting, it does provide you with everything you need for a great nights sleep, further bolstered by an impressive 8 year guarantee that is purchasable as an additional product. The guarantee offers further evidence that the brand and retailer believe in the product and it's easy to see why. A great purchase at a more than fair price point.


What Makes The Sealy Blackwell Traditional Spring Mattress Great?

Comfort Grade - Firm

If you find yourself suffering from back pain then you may want to look at an orthopaedic (fancy word for firm) mattress like this one here. Firmer surfaces put less stress on muscles while sleeping which might be exactly what you need to help your back

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

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.

Sealy's PostureTech Core Support system

Mattresses that come with a Posturetech Spring System help to assist with supporting of all pressure points on a human body. The result of this is that you end up with a far softer feel on the mattress that will naturally get firmer with additional pressure. The end result is a supportive and comfortable product

Power Pack

Unique to Sealy this is a type of system that has zoned springs along with firmer fillings for the mattress. This means that you end up with some really enhanced lumbar support

About Sealy

Sealy has divisions across the world with renowned manufacturing within the high-end bed and mattress segment for over 100 years. For the UK division of Sealy, the mattress factory is inset within the heart of Cumbria which makes an impressive 3500 mattresses per week.

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

A single sided mattress is typical for the industry and relates to how  a mattress has the comfort layer on one side of the mattress. only This means that the mattress only needs to be rotated rather than flipped. The benefit of single sided mattresses is that they require less upkeep in that there's no flipping, but also, there's less components involved in the creation which saves costs.

Online only

This mattress is not sold in stores and is instead an online-only model. That works quite well for us, since our core line-up or reviews and specification highlights are all based around online models.

Customer Reviews For The Sealy Blackwell Traditional Spring Mattress

Based on 59 reviews

Very happy

After spending money doing our house up, a mattress is a luxury item. After waiting 3 years we decided to get a new mattress. I found this mattress in the sale, it had a firm rating which I was worried it would be too hard for me. I was sleeping on a single duvet for comfort on our old mattress as I like the soft feel, but when this mattress arrived it looked fantastic. The delivery guys where brilliant and put it on our bed, that night I had the best night sleep I've had in years. Absolutely thrilled with it and have recommended it to family and friends. We have had the mattress for a few weeks now and both love it. Great product and great service.


Perfect for my bad back

Been sleeping on an old, saggy mattress for a while. Was getting increasing trouble with my lower back. I had no real proof that my mattress was to blame but thought it worth a go. Did some research on mattresses that might be better for me. This one was well reviewed and at a really good price in the Dreams sale. Always a bit of a punt buying on-line, but hit the jackpot with this one. Not only has my backache gone completely, but I now wake feeling much more refreshed - and look forward to curling up to sleep at bedtime. Feels well made so I'm confident that it's going to last.


Awww at last i can have a good night rest

I brought this Mattress this month and i can say its so comfy!! really glad i purchased it the delivery was on time the delivery men were courteous and very imformative by following up with the phonecall before to let me know that they would arrive this time and they were on time no worries the only thing i would say you cant turn the mattress over but you can rotate it to balance out the use of the mattress all in all im happy Thank you Dreams


Really comfortable single mattress.

This is a very comfortable and inexpensive single mattress. Perfect for the spare bed in our office room. The delivery service was exceptional with helpful drivers waiting for my wife to finish the school run before taking the mattress into the house, carrying it up the stairs and putting it in place, ensuring we were totally happy before they left. Can’t fault the service at all.


Definitely firm mattress!

I have had this mattress for 1 month. It is very firm which I like but feels a bit like laying on a board with springs underneath. I like the firmness level but would like a little more give in the top section. So I shall be buying a memory foam topper to go with it. In this regard it’s a little overpriced.


Amazingly comfy

This arrived on 14/02/2019 to which I'm sure you can imagine, my partner and I were very happy with. The first few nights weren't great but we realised after that we had the bottom of the mattress on top and therefore we were sleeping on the wrong bit! We have corrected and it's so comfy. We love it!


Brilliant Mattress

We needed a new mattress after the springs started poking out of the old one. This mattress is brilliant for the price. I have problems with my back and this a perfect mattress for me. It is firm but soft and has little bit of give that allows you to sink into it. We are both very pleased with it.


Lovely firm mattress

Bought this around 6 weeks ago and it has been amazing, my old mattress was really getting on a bit (8 years old is really pushing it a bit for a standard coil mattress) and this new one has been so much better, especially for getting up as I have far fewer aches and pains!


Fabulous nights sleep

I bought this mattress a month ago, it is fabulous nice and firm, best nights sleep in years, my fit tracker records my sleep and it’s gone from 3 hours a night to 7.5 I feel so much better. Another great feature it was in the sale so a complete bargain. Highly recommend.


ridiculously comfortable

I bought this 2 weeks ago and it is ridiculously comfortable. I have a really bad lower back pain and with this product my back is beginning to feel alot better. The bed moulds to my shape to give me an ideal peaceful sleep. I would highly recommend this matteress.


Great mattress!

I bought this a month ago and have been getting good night’s sleep ever since. It’s very comfortable, quite firm and is exactly what I’m looking for. The delivery was made on time and the whole experience was smooth. Great value for what I paid for.



Read all the reviews for this Sealy mattress and wasn't disappointed. I've bought Sealy mattresses before and had no complaints. This was comfortable from day 1 and I'm definitely getting a better sleep. Would recommend this mattress.


So comfy

I’ve been suffering from sciatica for a long time and the pain was waking me most nights and getting out of bed was a mission. After my first night with the new mattress I woke up pain free and have hardly has night pain since.


Firm mattress for growing child

I bought this mattress to go on my toddlers first proper bed as he moved from his cot. I wanted a good firm mattress that would support his growing body & this is proving to be perfect with him sleeping through the night.


Not very comfortable

I got this product one month ago. It is not that comfortable. It is very hard. I am thinking about getting a new mattress already. I'm sure it is brilliant for someone who loves a hard mattress but it is not right for me.


Lightweight and comfortable

My dear old Mum Just got me a new mattress from dreams and it is just what I wanted. Really comfortable and lightweight. I have disability issues and find the mattress easy to move about when I change the sheets


Finally have a good nights sleep!

As a teacher - I really need a good nights sleep! Beforehand I had an awful thin mattress. This has great depth and is the perfect mix of soft and firm! I’d recommend it to everyone, and it’s a good price!


Very comfortable

This was a new mattress fo go with the new bed frame in our other bedroom. We tried it for a night, and it was very comfortable. It is quite a firm sleep, but that is what we prefer. Nice and supportive.


Feels like I'm sleeping on a firm cloud

I struggle from back pain and finding a comfortable mattress has always been difficult, until now. This has to be one of the best mattresses I've ever had and genuinely look forward to going to bed now.
