This was a flawless experience. The day my new mattress arrived it was packaged perfectly! I removed it from the box, read the instructions and voila!! The mattress bloomed to the king size I ordered! The cooling mattress cover is exceptionally soft and cool. I feel the cooling difference even through my sheet. It is medium firm which is the right fit for me. This mattress is well worth purchasing! I’ve slept sound ever since this mattress arrived at my home!
