I ordered the Full size bed for our guest bedroom. Shipment came quickly/on time. I rolled it out onto the bed frame and removed the plastic. It QUICKLY opened up and I would say it was ready to sleep on in about 10 minutes. 1 hour later and its full as can be and we have our sheets on, ready to go. The mattress seems pretty good (first day review here). I would say that for memory foam, this mattress is pretty firm -- which we like. If you are looking for a soft/squishy mattress, this is probably not for you. If you like a firm mattress that is soft enough for those pressure points, this is great. I will update the review if any issues arise, but so far it looks and feels nice!
