I ordered the foam mattress for my daughter, age 18, because I have a Nova foam mattress from xxxxx over a year ago and have had no issues with support on it at all. When Overstock offered foam mattresses I looked into it and read reviews for months on them. I opted for the bodipedic based on reviews/price and have found that after my daughter has used the bodipedic mattress for 6 weeks there is definite signs of wear on the area she sleeps in, it has become extremely mushey while the other side remains firm. I ordered another mattress for my son, age 23, but a different brand of foam mattress from Overstock, a Comfort Dreams, I selected the firm option, which arrived on 11-12-10 I will write a review on it also after he uses for 2 months or so. as for now I will rotate my daughters bodipedi mattress and save up for another foam mattress and will never go back to a coil spring mattress. I recommend reading reviews especially when there is no return policy on mattresses with Overstock. I have been very pleased with all other purchases with Overstock.
