SERTA® Modern Series™ 8" Medium Firm Gel Foam Mattress - Double/Full

Q: Do I need a mattress protector for a full size mattress?

A mattress protector is highly recommended. It helps keep the full size mattress clean by guarding against spills, sweat, dust, and allergens, and it can significantly extend the life of the mattress in kids' rooms, guest rooms, or primary bedrooms.

Serta Modern Series mattresses deliver cutting-edge comfort at a great price point, featuring gel-infused memory foams and a convenient mattress-in-a-box design – all proudly crafted in Canada for today’s lifestyle.
