I bought this mattress for my 20 year old son in college. The Linen Spa replaced a 6 year old Serta that started sagging in different places. He says that the memory foam is very dense compared to his traditional spring mattress. However, he has slept quite well for the past several days he has had this one. I debated between the 10 inch thickness vs. the 12 inch. This mattress is plenty thick enough, as the 12 inch would have been much too high for his West Elm bed frame. I'm curious to see how this will hold up over the next few years but so far so good!
