Rotate Seasonally: Rotate your mattress 3–6 months to even out wear and prevent sagging.

Support Your Base: Pair with a sturdy slatted foundation or adjustable base to uphold your warranty and maximize support.

Create a Sanctuary: Complement your king mattress with breathable, high-thread-count linens, blackout curtains, and soft lighting for restful ambiance.
