We just purchased our third Serta mattress in over twenty years of marriage. We would not purchase any other brand of mattress. We are so confident in the quality and comfort of this brand that we purchased the third one on the internet and had it delivered without so much as having touched the product. And, we are not disappointed it is the best mattress made!!!. We have slept on many other mattresses at hotels, family's guest rooms and home away rentals. This is by far a better mattress.
