  • Size:

    When it comes to mattresses, one size definitely doesn’t fit all. The mattress should be longer than the tallest person sleeping on it. The bed width should allow enough space to fold your arms behind your head without going beyond the mattress edge or touching your partner’s elbows (for two adults, we recommend either a queen or a king).

Overview & Specs

Serta SmartREACT Southton 15” Super Pillow Top Mattress
You will feel confident when you switch to the Serta SmartREACT™ Southton Super Pillow Top Mattress. This mattress features an innerpanel upholstery layer that separates the pillow top from the rest of the comfort layers below, which adds a level of comfort to the mattress. The Serta® PillowSoft™ Foam gently contours to the body providing enhanced cushioning while the CoolReaction™ Gel Memory Foam provides pressure relief and helps to reduce heat build-up at the sleep surface. Hundreds of individually wrapped, slow recovery coils work with the foam layers above and below to continuously adapt to the contours of your body without any of the unwanted springy feel of other support systems. Experience the benefits of a good night’s sleep with the Serta SmartREACT™ Southton Super Pillow Top Mattress.
