First time purchasing a mattress NOT from a local store. Nothing to fear ... Wayfair made it easy to select the perfect mattress for me. Shipping was super fast - second day from submitting order. Came packed in a rectangular box. Just had to cut the "air compressed" plastic bag the mattress had been rolled into and WOOSH !  The mattress flopped open normal size. My choice was to let the mattress sit for the full 72 hours before placing on the bed so it could retain its full size. Since then ... nothing but pure comfort and sweet dreams. I would purchase another from Wayfair again. Great bargain.
