All of our beds fit standard size mattresses, but we recommend low profile mattresses for the best fit.
For the best fit and safety, we recommend low profile mattresses measuring 5 inches thick for all of our beds. We do not recommend exceeding a mattress thickness of 8 inches.
Our twin trundle bed also fits standard twin size mattresses. We recommend a maximum mattress thickness of 6 inches for our trundle bed for the best fit underneath your main bed.
