The Serta Sleeptrue Firm is a 6-inch full-size memory foam mattress sold compressed in a box. It stacks three layers: gel-swirled memory foam on top, a Pillow Soft Aire cushioning layer, and a dense foam core for edge-to-edge support. The thin profile and firm feel make it a natural fit for bunk beds, trundles, day beds and guest rooms, where thicker mattresses often don't work. Against thicker all-foam rivals it gives up depth and plushness, but it costs less and fits frames that a 10- or 12-inch mattress won't.

This 6-inch full-size mattress has a gel memory foam layer and a firm feel. The cooling gel is swirled into the memory foam to improve airflow, release heat and contour to the body. It has three layers and a tight top.
A Serta Foam Core at the base gives consistent support from edge to edge. A Pillow Soft Aire foam layer adds cushioning and airflow. The soft, breathable cover is polyester or a polyester blend.
The mattress works with bunk beds, trundle beds and day beds, and it suits a kids room, dorm room or guest room. It arrives compressed in a box. Unroll it and let it unwind. It can take up to 72 hours to fully expand and one to two weeks to air out.
