Review: Sleeping better! - Instead of buying a new mattress we opted for a topper. This one is really nice and comfortable! Great price also! Just make sure you have deep pocket sheets.
Review: I continue to love this topper! - We bought our king size hybrid mattress on desertcart and actually still really like it but I have pain issues where I like to have the option to make my bed softer when I want and more firm when I don't. This topper makes our medium firm bed so much softer while still maintaining the support of the mattress. I love this topper! It was a great value for the price and after about a month or so it continues to be just as plush and thick as the first night . I'd love to buy another one in a queen size for our guest room. It keeps it's shape and stays in place. I was going to buy the 5 inch option but I'm glad I didn't because our fitted sheets just barely fit with the topper and mattress pad . Our mattress is about 8 or 10 inches so the 3 inch topper is perfect. I highly recommend it!
