## Customer Reviews

### ⭐⭐⭐⭐⭐ So comfortable. Very supportive, Very good quality, Great price,
*by H***N on 18 January 2025*

So comfortable. Very supportive, Very good quality, Great price,

### ⭐⭐⭐⭐⭐ Very impressed - description correct
*by S***H on 4 March 2025*

This mattress is thick, it is firm and very supportive.We have only had it a few days however I am over the moon, it is so comfortable and is helping with an old hip injury I have. The thickness as described is correct.

### ⭐ It will not last for 5 years I can assure you of that and the warranty promise is fake
*by F***X on 6 June 2024*

Zero empathy about the real issues when contacted to inform the mattress has lost its integrity quite significantly while still under warranty. They talk to you like robots 🤖 “ you have not met the warranty guidelines” and all of this they have determined by the pictures I sent, perfect science! For context, different sections of this mattress dip in quite badly and it becomes very uneven. My advice, DO NOT BUY THIS MATTRESS. It looks perfect at the start but it really does lose its integrity quite badly in a way that is dangerous for the body posture, I mean very dangerous as I was waking up with pains on different parts of my body and sometimes had to slot my arm in the arc of my back or even an extra pillow to provide some balance, so extremely bad for your back. The 5 warranty also is just dishonest and a complete click bait” - they will ask you to send pictures and of course the pictures won’t tell them anything, so they won’t honour any warranty. They will give you the spill about guidelines that you never knew about because actually there was no information shared about the terms of warranty at point of sale. All just a big cun.
