    Great quality & so comfy
  

*by A***R on Reviewed in the United Kingdom on 22 September 2024*

Bought this for my daughter at Uni because her mattress is very springy & not that comfortable. Item arrives well packed. Very good quality, easy to fit onto the mattress. This topper is so comfortable, lovely & thick. It’s made such a difference my daughter loves it to sleep on. The price is great too. Highly recommend

    Good & comfortable
  

*by H***Y on Reviewed in the United Kingdom on 28 November 2024*

This is good, it is thick as advertised & has made a difference to my sleeping taking the edge off my hard (Chosen to be) mattress, it had become a little uncomfortable & the topper made all the difference.It’s not one of those fluffy all air toppers, it has more substance & takes the pressure off.I recommend this Topper.

*by Y***E on Reviewed in the United Kingdom on 23 October 2024*

Very pleased with this purchase.  It's very comfy.  After having lots of nights sleep with springs in my back, this mattress topper has done the trick.  The topper has made it possible for me to have a good night's sleep on my old mattress.
