The Serta® Senna Firm mattress offers the feel and tailoring of a traditional firm model and is the firmest mattress offered at Sam’s Club. This mattress is best for those who are used to, and prefer, a harder sleeping surface.

The Senna features Serta’s exclusive Verticoil Premier® innerspring, a patent pending coil design that provides 35% increased surface coverage when compared to other value-priced innerspring systems. More surface coverage results in an increased ability to react and conform to the individual contours of the body for proper support throughout the night.

Serta® has been a leader in product quality and innovation for more than 75 years. Thanks to Sam’s Club Everyday Savings, Serta is able to offer you amazing values on our premium mattresses. Plus, every Serta purchase made at Sam’s club is backed by Sam’s 100% Satisfaction Guarantee so you can rest assured in your purchase.
