In full agreement with comment above. We already had a topper from Raskelf and then tried a cheaper version off the internet. It was cheap and not a patch on the one at Raskelf so we got rid of that and bought another one from then.We did have some cheap 2" memory foam, it was OK but not a patch on the Raskelf which seems vastly superior to all the others. You do have to pay for it though. We paid £200 for a double!
