I was very hesitant purchasing a memory foam bed online, but with numerous discussions with the overstock chat rep and researching I made the final decision to purchase this 13" memory foam bed. I was worried that the first night I slept in the bed I would not like the bed after owning a ******* and ******* plush pillow top mattress for years. I slept so sound the first night, I was actually surprised. I am extremely happy with this purchase of this particular memory foam mattress, happy I went with the 13". I also purchased a platform bed so I only had to purchase the mattress and not a box spring. I have no regrets at all with my purchase. Overstock was extremely helpful with all of my questions.Now we are going to purchase the same exact mattress for my mom. I will highly recommend this memory foam mattress thermo gel cover bed. You will not be unhappy with this bed, it is well worth the money. So happy I decided to purchase a memory foam mattress.
