Thought I would try this topper after buying a new matteress which was hybrid memory foam but it was hard, I ordered after reading the reviews on different web sites and amazon, purchased through amazon it arrived with no problems (a day earlier than expected) I followed the instructions and left if for a whole day went to bed that night and had one of the best nights sleeps in ages, I suffer with a bad back and aching hips and my husband has a bad back also, so far we have had no problems with waking up in the night with aches and pains. I thought the price we paid was reasonable, a lot less than other famous brand matteress toppers! Although we had a 30 day trial period we won't be taking advantage of it! Really please would definately recommend to family and friends and anyone else who asks!
