This is my first Memory Foam mattress...very impressed. Yes, it does take a bit of adjustment to get used to from a standard coil mattress. Two months in...no complaints, thus far. I happened to choose the firm option. Since this is not a light decision for many people including myself, I comparison shopped locally and on-line. I couldn't be happier with this mattress from the Big "O". I wanted the name, the firmness rating, the size and the price. They all had to jibe; and yes, read the reviews, by all means. The leading name brand in foam mattresses (you know who I am talking about...grin) was just WAY out of my budget, and alternatives locally rated from so-so to not bad. Then, surcharges came rolling in to snatch the sale from certain victory. Some quoted delivery charges (I have a small car) were simply ludicrous, gouging and frankly insulting. The big retailers online were reasonable alternatives, with Great Offer Stock winning out for size, quality, price and firmness. I highly recommend this queen size Serta mattress. Thanks Big "O"! Peace out.
