I’m really disappointed with this product. It’s utterly useless and so thin and flexible that it’s definitely not orthopaedic.

The topper wasn’t right I think the foam was a king size but the silent night cover was a double. We took the cover off and thought we’d just use The topper without it but we had to air it out first because the foam absolutely stunk it made my whole house smell of something horrible, we even put it on the washing line to air out for a whole day and it still didn’t get rid of the smell. Tried again several days in a row still the same issue even sprayed with febreeze so much we used two bottles of it and the smell didn’t shift. In the end it was taken to the tip. Luckily Wayfair refunded me after showing pictures and explaining the situation to them.

This is just what i needed to firm up my mattress. Seems good quality.

after a few times using it we decided to take it off due to constant puckering up & the mattress topper was to big for the overcover.

What a difference this makes , getting good night's sleep now . I asked for firm topper , and it's firm
