My friend had a memory foam mattress and she told me she sleeps so well on it. I have tried one at a mall long long time ago but it was little expensive so I just kept using a regular spring mattress. but one day I found this Serta memory foam mattress and it was very affordable, so I decided to purchase. It came in a box rolled up and vacuum sealed. The first day I slept on it, I slept so well I had so many dreams in one night. Before if I get up once it was very hard to go back to sleep, but with this you can go back to sleep in no time. When I have 30 minutes in the morning I can sleep so deep for just 30 minutes. It's hard enough but still my body sinks slowly and I feel no pressure points.This was the best investment I ever made. I recommend this to people with sleep problems, back pains...etc. I love it!!
