Hubby thought we needed a new mattress to replace our 13 year old memory foam mattress. After shopping at various local mattress retailers and confirming that a firm gel memory foam mattress was what we both preferred, we ordered it on Great Offer Stock. Delivery was very prompt and the mattress arrives folded down to about a 4 foot long roll -- about the size of a heavy bag boxers practice on in gyms. It sprang into shape very quickly once the vacuum seal was broken. I guess hubby was right (don't let him know) about it being time for mattress replacement, as we both have been sleeping very well since this arrived. I can't speak for its durability -- it says it has a 15 year warranty ( pro-rated ) but the way I see it, for the price we paid for this one vs the old mattress 13 years ago, even if it only lasts 5 years we are well ahead of the price paid -per-year-of -use with the old mattress. Glad I made this purchase.
