Have had this mattress at almost 3 weeks. So far, so good ! It really is a very good mattress and has shown no unusual wear. I am sleeping through the entire night and waking up with no more pains. Will track it very closely because of Sams Clubs 3 month guarantee. This mattress was delivered 2 weeks early. Recommended.

I was expecting a rock-solid mattress based on the "ultra-firm feel" description, but this queen-sized mattress is more like between a medium and firm. The product label is miss leading and confusing: "Sealy Posturepedic Plus Spring Anderson Tight Top Ultra Firm Feel Mattress." What does this mean, "ultra firm feel?" Given the overwhelmingly positive reviews about this mattress being truly firm, I suspect I received a defective product.

Lost support within a couple months. Have had it 3 years—it is full of divots , lumps—not a good mattress at all. Firm? Not.

(Written after owning this mattress for one week) This mattress is supposed to be "ultra-firm" but in reality is more like a medium. I purchased a king with the associated box springs and have not had a single night of decent sleep without any type of back pain from my hips sinking into the mattress while laying on my back. When getting out of the bed after 4 or more hours, the mattress seems to be sinking more than normal and collapsing. This seems to be due to lack of quality control because the majority of reviews on this mattress are that it truly is firm.
