Know before you buy
The X4 DUAL KING features independent support zones on each side of the mattress. This allows you and your partner to adjust the firmness or support level individually without affecting the other side of the bed.
The mattress is engineered to provide a seamless surface across the entire sleep area. While the internal support systems are independent, the top comfort layers are designed to minimize the sensation of a split.
This mattress is compatible with most standard flat foundations, platform beds, and adjustable bases. We recommend ensuring your base provides a solid, level surface to maintain the integrity of the dual support system.
Yes, the personalized support settings are designed to accommodate various sleeping styles, including side, back, and stomach sleepers. Because you can customize each side, you can tailor the surface to your specific pressure-relief needs.
The dual-configuration design inherently limits motion transfer between sides. Because the support systems are independent, movement on one side of the bed is largely isolated, preventing it from disturbing your partner.
