Sealy had excellent customer service. Not walmart

We ordered this mattress and left it alone to finish blowing up to a queen size bed. After 24 hours we still had a major dent in it. I called walmart and was told to put the mattress back in the box (not possible) and I got the same response from fedex. I finally called Sealy with the 800 number they gave on the box. 2 days later they shipped up a brand new matress and told us to throw away or donate the old one. While I wasn't happy with the first damaged one, I was really impressed with the customer service and the way they guaranteed their product and how they responded with a new mattress.

Finally A Mattress Made For Us %26 Me

Went from a pillow top mattress to this one and the difference is uncanny- took away my body aches - wake up not hurting and well rested - love how this mattress contours to my body shape- it definitely stays cool and comfortable- my partner's movement in the night doesn't wake me or I wake my partner - Love the price point of this product and will be purchasing another one in the future - added to my purchase later list - very pleased with this purchase- worth the price - excellent quality-

I would HIGHLY recommend visiting a mattress shop… have them help you figure out what firmness you need based on how you sleep… then visit Walmarts website… find something comparable for half to a third of the price. Armed with that information… this mattress was perfect for me as a side/ stomach sleeper.
