The gel memory foam aligns the spine and evenly disperses body weight to relieve pressure points. This is a game changer for anyone who has struggled to find a mattress that caters to their sleeping habits.
Additionally, the strong edge support of the Ruoysun California King Mattress enhances its stability and reduces the risk of rolling off during nighttime movements.
