I purchased this "SPA SENSATIONS 3'' AIRFLOW VISCO ELASTIC TOPPER for my granddaughter. She was having a problem sleeping and thought she made need a new mattress, but was unsure of what kind of new mattress she wanted to buy. I researched the various toppers and chose the Spa Sensation 3'' because of the VISCO quality. She told me she liked the height of her mattress with the topper and she finally got a good nights sleep. She just started college and was happy that we found a cheaper alternative to buying a new mattress. She also told me she was not sure whether she wanted to buy a memory foam mattress or if she would even like the memory foam. She said this new topper gave her the oppurtunity to experience what a memory foam mattress would feel like. She loves it. So it looks like her next new mattress will be a VISCO memory foam like the materials in this new topper. I would suggest others made find this a good alternative to a new mattress. IT WILL SAVE THEM MONEY!!!!!!!
