What Makes It Great

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.

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

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

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.

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

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

Questions and Answers

Do you need to turn this mattress as well as top to toe?

Answer: We recommend that you rotate your mattress regularly - rotate head to toe weekly for the first three months, then every month thereafter. This mattress is not double sided and therefore means that you do not need to turn it, as only one side is able to be slept on. Kind Regards, Dreams

Do you take away old mattress

Answer: Hi , Yes, we offer a recycling service. The cost of taking away your old mattress depends on the size of your mattress. This can currently be added at the checkout stage. You can read more about our recycling service here: Kind regards Dreams

will this be alright on adjustable bed.

Answer: Good morning, No, you will need to purchase an adjustable mattress for an adjustable bed. You can view our range of adjustable mattresses here: Kind regards, Dreams

If you can't turn it, does that not affect the lifespan of the mattress

Answer: No, having single sided mattress does not impact how long the mattress can be used for. Kind Regards, Dreams

What grade firmness is the mattress please?

Answer: The Sealy Blackwell Mattress is a Firm comfort grade. Kind Regards, Dreams

Hello, Are you able to tell me how much the double mattress weighs please?

Answer: This mattress will weigh 24.75kg. Kind Regards, Dreams

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.

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!

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.

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.

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!

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.

Great value for money and great quality

6 weeks into this and it has massively improved the sleep for both myself and my wife, who suffers from chronic back pain. The mattress is incredibly stable so when I move she doesn't

Great product for the price

I purchased this a few weeks ago in Superking and we are very happy with the quality as it was as the lower end of the price range. Great service from Dreams, couldn't be happier

New mattress

Delighted with product, the only reason only four stars it does not have handles to aid turning mattress especially as I have to do this single handed.

perfect for support

A great mattress is you need a firm mattress. really supports the body in the right places. The luxurious cover makes it the perfect nights sleep.
