SERTA PERFECT DAY FIRM 12" MATTRESS

The Serta Perfect Day 12" Firm Mattress is your ticket to a refreshingly supportive night's sleep, conveniently delivered in a box. This 12-inch firm innerspring mattress is engineered with a Custom Support Coil System, featuring hundreds of individually wrapped coils. This technology provides contouring, cradling support while minimizing motion transfer—so you stay asleep even if your partner tosses and turns.

Targeted relief is delivered through a Gel Foam Lumbar Support Band that reinforces support for your lower back and hips. Above the coils, comfort layers like PillowSoft® Aire Foam and QuiltLoft™ Memory Foam enhance cushioning and promote airflow for a cool, fresh feel.

Ideal for back and stomach sleepers who need extra support to maintain spinal alignment, the Serta Perfect Day is also adjustable base compatible and includes antimicrobial technology to keep your mattress clean and fresh. Unpack, unroll, and enjoy the firm, durable comfort Serta is known for.
