Make use of the space under your bed with drawer units. All beds (even twin size) can accommodate a drawer unit on each side. 3 and 4 drawer units are sized to the fit the bed length. For a queen, king or an extra-long twin or full bed choose extra-long when configuring your choice.
2 drawer units are sized to match up with a night table beside your bed. The night table will not block the drawers. Again there are 2 length options to match your bed length.
A Trundle Drawer or Storage Trundle can also be an excellent option for underbed storage of extra bedding or bulky items.
