[This review was collected as part of a promotion.] Serta’s Hello Dreams Firm mattress is firm, but not too firm. The mattress doesn’t give way on the edges like some mattresses do. So you can really utilize all of it. Besides the comfort factor I love the blue edging which will look crisp and clean for years to come.

Just received my new mattresses to replace my Members Mark hybrid medium firm twin XL that were too soft. Right away noticed that this Serta doesn't flex as much with the adjustable base And does have a removable cover. Hope it will be a great sleep.
