Hurts Back

Great support

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“I love this mattress! Great support unlike the memory foam toppers, and mattresses I have tried. Worth the investment to get this traditional spring mattress. As an older person I have found it easier to move about and the edges are very firm for sitting. Highly recommend!”
