### ⭐⭐⭐⭐⭐ Review
*by P***F on 9 January 2026*

I’ve had one of these naturalex mattresses before but in a king size. I loved it. It’s So light but still with the firmness. So when I switched to single beds I bought foam mattresses thinking they were the same! How wrong was I. They were ok but at £150 each, not great and way too heavy for me. So after 2 months I search for naturelex again and found this. I was worried by the price thinking it wasn’t going to be as good as the one I had before in king size. I was so wrong. This is amazing for the weight, making it easier to change and the firmness of the mattress. I will be ordering another to replace the other one I bought too. I guarantee spending £70 on this one will be so much better than spending £150 on a heavy foam mattress. These are amazing. Especially if you’re like me where you struggle with the weight of a mattress but like the firmness.
