The Serta® Willowby Plush mattress offers classic tailoring but has a little more “give” or softness at the sleep surface when compared to our firm models. The difference in feel comes from a slim, plush comfort layer at the top of the mattress. It does not have the additional upholstery layer found in our Pillow Top and Euro Top, so you will sleep closer to the support system of the bed. This mattress is recommended for those looking for some enhanced cushioning without going too far from the traditional firm feel.

The Willowby Plush 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. Plus, a slim layer of plush foam provides slightly enhanced cushioning at the sleep surface for added comfort.

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.
