Everyone’s making hybrid foam mattresses now, even legacy brands like Sealy, and Walmart’s blowing out their Optimum Posturepedic mattresses for crazy-low prices, while supplies last.
The only sizes available are Twin XL, Queen, and King ($290, $340, $490, respectively), but if those fit your needs for your own bed, or even for a guest room, these prices are way less than you’d pay at Amazon.
