This is a high quality Serta Crib and Toddler mattress. It is firm. It offers patented fireblocking technology and innerspring support for a sleepy baby. 4 air holes on each side for more breathability. The surface is water proof so no accident will leak into the mattress, making it very easy to clean and maintain. Dimensions 52'' x 27.5'' x 6''.

　　My baby used to take 4-hour naps on the bed and slept oh-so soundly through the night. I thank her quality sleep to this firm mattress.

　　I will also include a very cute, neutral colored mattress cover with this bed. A value of more than $200 from the retail stores, and ONLY $40.00 for you. Mattress and cover are in GREAT CONDITION. Come from a clean, smoke-free household.
