Great product! We just had guests in and both commented that the mattress was the most comfortable guest mattress they’d ever slept on - considering I’ve slept on the actual mattress several times, I can tell you that the comment can 100 be attributed to the mattress topper!  The directions said it would take 72 hours to properly puff up, but I’d say ours took only about 24 or just over. Shipping was quick and package was boxed well for transport.
