Finding a decent memory foam mattress topper is a nightmare as I know from trying. Not all sellers tell you the most important thing (in my opinion) which is the weight per square metre, the higher the better. These people do and their product id fantastic. Another important thing is the smell when you first open it. Mine did wiff a bit at first, but within a few hours the smell was gone, yes if you stick your nose in it there will still be a small amount of odour, but after you have left it the recommended time before you sleep on it all will be good. If you're looking for a quality mattress topper, look no further and get your wallet/purse out. Is it more expensive than some? yes, but quality costs more, remember, buy cheap, buy twice!
