The Serta Perfect Sleeper Splendid Slumber Medium 12" Memory Foam Mattress combines advanced cooling technologies and premium materials for a restful night’s sleep. Featuring HexCloud gel memory foam, Cradle gel foam, and Cool Twist gel memory foam, this mattress offers exceptional comfort and support. Its antimicrobial protection helps keep the mattress fresh by inhibiting odor-causing bacteria, though it does not protect against bacteria, viruses, or germs. Certified by CertiPUR-US®, the mattress meets high standards for content and performance. It arrives conveniently in a box, ready for easy setup—just unpack, unroll, and unwind. Compatible with most frames, platforms, and adjustable bases, this mattress is proudly assembled in the USA and comes with a 10-year limited warranty. Please allow up to 60 days for the mattress to fully adjust to your comfort preferences, as it may initially feel firmer and soften over time with temperature changes.
