At first I was very nervous to order a mattress without testing it out first. But having purchased serta products in the past I trusted it would be great. I'm 7 months pregnant and as every pregnant woman knows sometimes sleeping can be uncomfortable. I was suffering with back pain and waking up all night. Now I sleep straight through the night and the back pain has disappeared. If you are a looking for a firm mattress i highly recommend this product and the low price really helped with the decision making.
