Please indulge me if you have already discovered the benefits of memory foam as a way of enhancing your quality of sleep but to those who may not have I cannot recommend this product highly enough. There are memory foam mattresses which are good but cost a small fortune but you can also buy a memory foam 'Topper' for your existing mattress which works just as well .I`m lucky to be free from arthritis, muscular or back problems but if you have any of these conditions and find it difficult getting some quality sleep then this should be really beneficial to you. I`ve had one for a few weeks now and I find the improvement in comfort just amazing. This product is available in various thicknesses and density and while a decent one is still quite expensive they are far cheaper than than a full mattress. I bought a 2" one on Amazon(UK) which was the best value I could find anywhere. If you are having trouble getting a decent night`s sleep for whatever reason this is really worth a try.
