Came very quickly by fed ex. Ordered the king. After reading the reviews I ordered this and it is a true 10” if not a little over. I did let it sit out about 8 hours and then slept on it that same night. I do have back issues and have had a couple back surgeries and my young age of 40. It is a little bit on the firmer side and I probably think more do to having my other bed for about 15 years. I sleep great in it and wake up feeling better. It’s a great bed for the price for sure. I did order the platform bed and bedding as well from wayfair and love it all!!!! Great price and great bed for around 300$ king size. This headboard is the tiara upholstered platform bed in pepper color. Aegean comforter.  Hope this helps ♥️
