<p>Does anyone know approximately how deep the mattresses are? I recently found a nice 4" thick memory foam twin XL mattress pad on sale. My only concern is that a twin XL fitted sheet wouldn’t be able to fit over it and the mattress. Thank you for any insight!</p>
<p>you should be able to fit the sheets. you may want to look for deep pocket sheets. but deep pocket sheets are going to be hard to find in XL. As long as you dont care that the sheets don't look perfect or fit perfectly, you should be fine.</p>
