## Description

Silentnight Deep Sleep Ultimate Mattress Topper 1000 - king : desertcart.co.uk: Home & Kitchen

Review: Very comfortable, a good buy - I bought this after spending a night in a hotel on an unbelievably confortable bed. This mattress topper was advertised as being used by hotels, so I thought it might help with my bed. It was cheaper than memory foam, which also has a reputation for being uncomfortably hot. At first I was disappointed by how small the double bed size topper was. But actually, it fits well - just not quite to the edges - which means that I can still use my existing fitted sheets. It comes vacuum packed and very shrunk down. I followed all the instructions on fluffing it up and leaving it before use and it expanded to a decent thickness of softness. It seems to be fairly well made, with no obviously loose threads. There is elastic in the corners which holds it in place on the mattress. This has proved to be a game changer for my ageing body on my uncomfortably hard mattress. Not only that, but it's warm. Not sweaty warm, but cosy, comfortable, don't want to get out of bed, warm and comfortable. I've had the best several nights sleep for ages and feel much better as a result. I think it will fit in the washing machine as it is lightweight, compressible and should spin fairly dry, similarly to my quilt. I get the impression that my quilt is made of similar material, just less densely packed. It will probably need fluffing up again afterwards, but the stitched pockets should avoid too much clumping. I have recommended this to several of my friends because it is just so comfortable. I will probably get one for the caravan as well. Very pleased so far.
Review: Really works - I like to buy Silentnight bedding, this topper was for a new mattress that was harder than I thought, only needed a little one to help.my hip, I unpacked it and laid it out for the day so it could settle. It doesn't have corner elastic to tether it it goes right across the underneath of the mattress and it stays were its put top and bottom, fits perfect and definitely made my new bed comfortable to sleep on. For the money this topper is great, always packed well anyway and always on time. Highly recommend this topper.

## Questions & Answers

**Q: Is this 143 or 150 cm actual king size ???**
A: Hye, I purchased a Single Size Ultimate Topper which is perfect in every way.  I imagine you are requesting the width and confirm that 150cm complies with King Size as I believe it to be.

**Q: Is the ultimate deep sleep mattress topper encased in 100% cotton outer**
A: It is cotton on the top but not on the bottom it is also very thin

**Q: The product description states the topper is heated, is it?**
A: Good morning,

Thank you for your question. The product description is incorrect, please scroll further down to the section From the Manufacturer. This section has the correct information and i will have the Amazon team remove the product description section and replace it with the correct information.

I hope this helps and answers your question.

Kind regards,

Customer Service Team

### ⭐⭐⭐⭐ Comfortable and Flat, Just Could Be Thicker
*by S***Y on 3 March 2026*

The flatness is pretty good. It lays evenly across the bed with no noticeable sagging. It’s soft and comfy, though I gave it 4 stars because I wish it was a tad thicker for extra cushioning. Overall, happy with it!
