Specially made for use on trundle beds and top bunks, the Serta Alderbrook mattress set provides a supportive sleep surface with the quality you expect from Serta. Delivering a good night's sleep in a compact package, this quality mattress's foam core makes it a durable, lightweight option suitable for most any room.
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.
