Purple mattresses are not intended for use with a box spring. Our mattresses are best supported by an adjustable base or platform frame, like our Upholstered Bed Frame and Metal Platform. Meanwhile, our Flat Foundation adds proper support to bed frames that lack supportive slats. All of our bed frames and foundations are made specifically to support Purple mattresses, so you know they’ll be a perfect fit and protect your investment for years to come.
The best California king size mattress is one that provides the right spinal alignment, pressure relief, and comfort for your body type and sleep style. And for that reason — it’s a Purple mattress. Our patented GelFlex Grid is the only mattress material that instantly relieves pressure for pain relief and proven deeper sleep. Couples love Purple because the Grid sleeps cool, minimizes motion transfer, and adapts to every body type + sleep position. If you and your partner have unique sleep needs and preferences, Purple is best.
