Review: Additional comfort for a decent mattress - DON'T buy if you have an old mattress - First of all I am so shocked at the low reviews, people need to really readjust their expectations! If your mattress is old, uncomfortable and ready for the scrap heap then this is not going to miraculously transform it. You need a new mattress, or a thick memory foam topper that will cost well over £100-£150. This topper is designed to add an additional level of comfort to an already good mattress. If you have loose springs or dips in your mattress then this topper won't do anything to gloss over these issues! I also have to say that comparing the thickness of this to a summer duvet is out and out laughable!!! If you put this over yourself in summer you'd last 30 seconds before you were hyperventilating! Onto the review proper; what you get is a well made/constructed topper which is "smooshy". It has zero support, is flat and made specifically to add a little cushioning to your mattress. We have a good quality memory foam mattress with good support. We wanted this to add a little softness and it works a treat. It fits well over our mattress and meets the standard sizing for a king size. As I say DO NOT buy this for a lumpy, worn and ancient mattress, or if you have a bad back. You need to dig a little deeper into those pockets for that and fork out for a new one! DO buy this if you have a good decent mattress that isn't worn and has good support, but you just want to make it a little softer.
Review: Worth the money - Reasonably priced, excellent topper! My mattress was too hard. It becomes comfortable and I can have good sleep after adding this topper, recommended.

## Questions & Answers

**Q: Does anyone have long experience? How is the quality?**
A: I don't recommend this one, broke after 5 weeks. Foam inside is torn... I've had the newentor topper for 3 months, it's much better, both sleeping comfort and quality!

**Q: Does it get too soft? Because of back problem I can't sleep too soft**
A: Then the topper is absolutely not for you! I'm 160cm and 55kg, lying in a hollow, sent back immediately. Now i sleep on newentor topper, it has 2 layers and not so soft also not so firm, very happy with it.

**Q: I have a new Orthopaedic  mattress which is too hard.  Would this topper help at all please?**
A: Yes, it would. I bought a new mattress that was a bit hard for my back and this does the job perfectly. I absolutely love it.

**Q: This looks pretty thick - is it really going to fit into a washing machine?**
A: It's thick but the air pockets allow it to compress so if you squish it up it should fit in a standard washing machine. I have the king size and I can just fit it. I"ve had no problems washing it.

*by W***. on 12 January 2026*

Reasonably priced, excellent topper! My mattress was too hard. It becomes comfortable and I can have good sleep after adding this topper, recommended.

### ⭐⭐⭐⭐ Really comfy!
*by L***Y on 21 December 2024*

We had an older spring mattress in the house that was getting uncomfortable to sleep on as the springs kept popping up, but we purchased the extra deep mattress topper and you can't feel the springs at all! It's a really brilliant extra level of comfortable to add to the bed, especially for the price-point! It's very soft, almost like an extra duvet between you and the bed. It's not firm or like memory foam! We did initially think that it would be a bit thicker, I would say it's 10cm in the very middle but the sides don't have the same thickness! Another review mentioned that it seems like it wasn't filled up enough, especially for the extra deep version, and I would agree with that! That being said, it doesn't take away from comfort or functionality at all! It fits our double-bed perfectly, and helps with a good night's sleep. It also adds an extra layer of warmth, which has been an added bonus in the Winter months. I would definitely recommend! Edit: After a month of use, the mattress topper is still keeping us comfy and cushioned every night! We thought it would sink a little bit, but it's stayed the same and has been adding an extra bit of support to our mattress. It definitely keeps the bed VERY warm, just something to keep in mind! We would still recommend!
