This mattress topper absolutely made all the difference in the world for us. It is a well-made product that really does what its supposed to and very well! My husband and I had been sleeping on a futon fold-out bed, on an inexpensive futon mattress that was so uncomfortable that we could feel the cross boards of the frame within a month of use. We've used foam mattress covers before -- and our daughter uses one at college -- but this product is quite another and better animal! The density of the foam of the topper and the gel technology really kick it up to another level. Especially for the price... I would recommend that you purchase a protective cover for it, if you can manage it, when you make a purchase. We have pets and had a close call a week after we bought the topper! Highly recommend this product. BTW, there was no odor at all that we recognized...Also, I have a lot of allergies and have not reacted to the topper.
