Serta Perfect Day 12" Firm Mattress-in-Box
The Details
The biggest Perfect Day — 12 inches of Firm support. Top of the Perfect Day mattress-in-a-box line: wrapped-coil support with PillowSoft® Aire comfort foam and Box-to-Bed in Seconds™ setup, with a thicker support core that feels noticeably more substantial than the smaller profiles. Made in the USA with global components.
Best for: Main bedrooms when you want value over luxury, back/stomach sleepers, heavier sleepers who need real support without paying iSeries NXG prices.
Sizes: Twin, Twin XL, Full, Queen, King, Cal King.
Starting at $499 (Twin). As low as $13/month with Synchrony financing.
