My Serta Perfect Sleeper (Queen / Ultimate / Plush Pillow Top) Innerspring Mattress is an amazingly awesome choice. When it comes to getting a night of the best sleep out there. Serta hit a bullseye with this mattress. Love that Cobalt Blue. Like sleeping on a cloud. The design, craftsmanship, and quality of sleep is SUPERB. Did I mention the matching foundation is a plus. Great nights ahead! Thank you Serta!
