Rated 5 out of 5 by from Give your sleep a massive upgrade! This mattress is a game-changer. We previously owned a locally-made mattress that barely lasted 3 years before completely falling apart and causing poor sleep and joint pain. The firm Tempur-Pedic units feel overly hard until you actually sleep on them. You slowly sink in just enough for proper support and sleep oh-so well. No regrets with this purchase!

Tempurpedic is so amazing with this memory foam mattress. It is just right, not too soft, not too firm. I would definitely recommend this item.
