The mattress size of the Lotus crib is 24 inches x 42 inches.
We recommend the Lotus Crib Sheets that we have on our website as they are compatible with the Velcro tabs (shown below) that attach the mattress to the base of the Crib. These tabs keep the mattress and sheet secure to the Crib's base to keep your little one safe.
The Velcro tabs are a mandatory feature that secure the mattress to the base of the crib as required by the Federal Safety Standards. The sheets have slots for the Velcro tabs so that the sheet, mattress, and Crib are all secured safely together.
