Just unroll, and the bed does the rest! Shipped VERY fast-I bought the Sealy deep pocket sheets (300 th ct) as well with this mattress from Overstock, and they look and fit and FEEL fabulous! No smell with this mattress, and we had to keep it sealed up for three weeks before our new bed arrived! I LOVE that there is no motion transfer in this bed, with a husband and two Pugs, and sometimes our cat too (on my head)-there is alot of joshing around throughout the night, and every time it would wake me up. I woke up this morning to an empty bed and didn't even know anyone was gone! A MIRACLE! I bought the soft version of this bed, and it feels just perfect, still "firm" overall and contours perfectly to my body and back. Highly recommended!
