Ideal for children transitioning into a "big" bed from a crib or toddler bed, or for those who prefer a firmer mattress, the Serta Mockingbird mattress provides a firm, supportive sleep surface delivering quality, restorative sleep. Serta's 532 Continuous Support innerspring coil design delivers a stable, durable surface that absorbs body movement and provides target support. Layers of Serta Support Foam and PillowSoft foam add pressure relieving comfort while maintaining a nice, firm feel at the mattress's surface.
10 Year Non-Prorated Warranty.
Low Profile Mattress Sets include a foundation (or box spring) that is approximately 5" in height instead of a standard foundation, which is approximately 9" in height. (Note: Therapedic brand low profile foundations are approximately 3" in height.) A great option for little ones just transitioning to "grown-up" beds, low profile foundations keep children safely closer to the ground.
