The mattress that broke the internet just got an upgrade. The Purple Hybrid mattress uses Purple’s patented Smart Comfort Grid™. The unique 2” top layer adapts to your body and stays cool for superior comfort, support, and better sleep. Purple has added a new base layer of individually wrapped responsive-support coils to enhance the overall comfort and durability of the mattress. The combination of the Purple Grid™ and patented responsive-support coils augment the responsiveness and open airflow for even more adaptive cool, No Pressure® Support. This mattress is perfect for sleepers who like their mattress a little on the firm side.
