This mattress is expertly compressed and rolled into one box that ships straight to your door. Simply unbox, unroll and this mattress does the rest, expanding to its original shape within 72 hours.
While it may take up to 72 hours for your mattress to fluff up to its full height, it is safe to sleep on the first night. Jumping, walking and sleeping on your mattress actually helps with decompression! Learn more about setting up your new mattress.
