The Kirkland Signature Lakeridge Firm Tight Top Queen Mattress is a premium hybrid mattress crafted by Stearns & Foster, a Sealy brand, exclusively for Costco. Standing 14 inches tall, it delivers a firm, supportive sleep surface with a smooth tight top profile — ideal for sleepers who prefer minimal sink and strong spinal alignment.

The mattress features an IntelliCoil pocketed coil support system that responds to body movement independently, reducing motion transfer and providing targeted support across different body zones. The comfort layers include TENCEL fabric on the cover for moisture-wicking breathability, along with high-density foam engineered to cradle pressure points while maintaining the firm feel. The Precision Edge system reinforces the perimeter of the mattress, maximizing the usable sleep surface and providing stable edge support for sitting and getting in and out of bed.

As a Costco exclusive under the Kirkland Signature label, this mattress is backed by a 20-year manufacturer warranty and Costco's generous return policy. It is produced by Sealy Corporation at their Richmond, CA manufacturing facility and is designed to compete with premium innerspring hybrids at a significantly lower price point.
