A solid mother in law approved item
The mattress was purchased for our guest room, the most regular guest is the mother in law. You can rest assured, if there was anything wrong with this mattress I would be painfully made aware of it. The repercussions of any material or workmanship shortfall would have been highlighted in great detail, and each of them would have been blamed on me, and in turn, added to the list of inadequacies of which, apparently, I have many.
This particular mattress has passed the mother in law test, in my world there is no tougher critic!

Not strictly as advertised.
I was replacing two firm Silentnight Miracoil mattress’s that I was very pleased with after many years service, these were nothing like the same. Firstly they are not 5′ as a King size bed should be, they were 150cm, 59″ which did not cover the 5′ divan base from my previous bed. Secondly they are quoted as 25cm high, only 22.5 depth. Thirdly, they are quoted as medium/firm, they are extremely firm, no give at all. Had I not disposed of my previous mattresses I would have returned them. Eased the problem by buying a 5cm memory foam topper which has made them much better.

Perfect size, firmness, quality and cost!
I initially purchased this to use as an interim bed mattress, while I decide exactly what to do with my bedroom in terms of decoration, changes and settings. I had lower back disc surgery and suffer with back and leg pain alot, therefore need a firm mattress without it feeling like a rock! I have tried at least 5 other brands of mattress including, Simba, Eve, Emma, Tempur, but after a few weeks they all disappointed me in terms of comfortability and durability, not to mention how costly they are! I have had this Silentnight Miracoil Mattress at a 1/3 of the cost for almost a month now and so far it feels perfect. A definite risk worth taking and if it is not suitable, Cost Co assured me they will take it back so I can’t ask for more!

Silentnight Miracoil Memory Cushion Top Mattress
Initially, I thought the mattress was going to be too firm when it arrived. Surprisingly though the addition of the memory foam top layer made all the difference. Really good nights of sleep since. Great value for money.

Not for me!
Nice to look at but uncomfortable. Bought this to go on new bed we bought, but had to return as was so hard like sleeping on a door might be ok for some people but I found I was waking up with bad back and aches and pains

Very comfortable
I bought two of these mattresses for my kids and they find the very comfortable and a massive step up from what they had previously.

Just sleep on the floor
I’m very used to a hard memory foam mattress, but this takes it a little far. This is absolute torture and just couldn’t get a good nights sleep on it. There is hardly any movement in the mattress which I guess is a mixture of very very tough springs and the memory foam.
Ended up having to purchase an extra memory foam topper to go on top of this mattress at an extra £90 from thinkassemble.co.uk, which thankfully has done the job.
I would look at the other mattresses and toppers thinkassemble.co.uk do before this mattress which is just painful!!!

Very Comfy
My mum bought this matteress and it was well worth the money.She suffers really bad with arthritus so it’s difficult to find a proper matteress so she can get a good nights sleep.After buying this one, she’s more than happy and finds it easier to sleep without keep waking up.

Good value for money.
Took a few days to get used to it, but it’s ok on my bad back, not too firm, not too soft. My last mattress lasted 20 years, not sure this one will, at £300 good value but remember the saying ‘you get what you pay for’.

Another quality purchase
This is the third mattress we have ordered from thinkassemble.co.uk. As usual, it has been very easy to order, and being able to choose my delivery date is a massive plus. Delivery was as planned, stress free and the delivery guys were efficient and friendly. Loving the mattress – the usual quality and value you expect from thinkassemble.co.uk – hence being a repeat purchaser. Will not buy from anywhere else – you know what you are getting from thinkassemble.co.uk

Too hard!
Very hard mattress. I knew it would be firm but it is as hard as a brick. No memory foam at all.

Just what I needed
This mattress is just right if you want on that is firm but soft, I find it just right for my needs, I do like a firm but not hard mattress and I am sleeping much better than I did on the old one.
My partner likes a more soft mattress and he did struggle the first couple of nights but has got used to it now and finds it good.
Ordering was easy and delivery was as described with no delay once a date was provided, the men put it in place after taking off the packaging and adhered to covid distancing guidelines.
I would recommend this product.

Good nights sleep at last!!
I bought this mattress after buying two others both of which were so bad they gave me chronic back pain. With two knee and two hip replacements the miracoil i bought from costco is fantastic, giving great back support and yet soft on my joints when i turn over.
The delivery service was great and on the day and time advised. Thank you for a good nights sleep!!

Spare room bed mattress
Mattress is being used in spare room to accommodate grandchildren < 10yrs. They like it. Delivery was not accomplished on original day was arranged even though someone was in the house all the time. 2nd date arranged was OK.
