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.
