I received this bed in a box mattress to test out and review and am I happy I did! I have to say I was a little leary of a bed in a box but I was pleasantly surprised. This has got to be the most comfortable bed I have ever slept on. I sleep through the night with out waking up achy and sore. It is amazing! Thank you for this testing opportunity. My daughter is already begging me to get her one too! I highly recommend!!
