KIDWELLY Twin Bed w/ Trundle, 78 1/8"L X 41 1/2"W X 60 5/8"H, 198lbs. Just like the beautiful coastal properties seen on television, this bed is inspired by the cozy and airy feel of the common beach house. Knowing the kind of fun that will ensue when this slightly elevated bed is assembled, the rails were added for extra safety and assurance. With its trundle underneath, it is also quite functional--extra storage is close at hand when the trundle is converted into a three compartment drawer.
