Good Morning! it's 30" wide, 20" deep, 10" thick. The top is 2" thick so the drawer front is 8" high, and the lower shelf has the same horizontal dimensions and is 2" thick. It's mounted so that the top is 30" off the floor, and 10" separates the two pieces. You can't see it in the photo but there is a grommet in the top at the back left to run the power cord for the lamp to a wall socket right underneath, so the drawer is about 4" shorter. The bed is a California King. Cheers!
