About this item

The Serta Perfect Sleeper® - setting the standard for great night’s sleep for more than 75 years.


The Perfect Sleeper® Knollcrest Plush Super Pillowtop is one of the softer and more luxurious feeling Serta mattresses at Sam’s Club. The Knollcrest model features a rich layer of Serta’s Next Generation Latex foam – a hypoallergenic, breathable and resilient foam that responds instantly to the body for superior pressure relief. It also features Serta’s exclusive Cool Balance™ Fabric Technology in the cover to help maintain a comfortable sleep surface temperature throughout the night. This mattress is recommended for those who prefer the additional upholstery layer and a luxuriously soft feel.

The Knollcrest Plush Super Pillowtop mattress features Serta’s exclusive Advanced Comfort Quilt® to help reduce tossing and turning and the Continuous Support® Innerspring for proper spinal support throughout the night. This mattress also features Foam Encasement for enhanced edge support and an extended sleep surface.

This Perfect Sleeper mattress was designed with input from the National Sleep Foundation, an independent nonprofit organization dedicated to improving public health and safety by achieving understanding of sleep and sleep disorders, and by supporting sleep-related education, research, and advocacy. Serta and the NSF have joined forces to help consumers get the most benefit from their Perfect Sleeper purchases by developing an exclusive educational booklet that comes with every purchase of this Perfect Sleeper mattress. Additionally, every Serta purchase made at Sam’s Club is backed by the Sam’s Club Member Satisfaction Guarantee so you can rest assured in your purchase.
