Who the Serta Perfect Day Overnight suits

The Serta Perfect Day Overnight is a good fit for back and stomach sleepers, anyone who wants a firm coil bed at the lowest Serta price, guest rooms, first apartments, rental suites. Side sleepers usually want the Saturday or the Sunup instead.

How the Serta Perfect Day Overnight compares

The three Perfect Day beds share the same coil unit. The Saturday adds a Euro top with a gel memory foam layer and lands between firm and medium; the Sunup is the plush Euro top for side sleepers. The Rockwell Resort is the lower-priced firm coil bed without the Serta name or the 10-year warranty; the Serta Classic line is the step up out of the box.
