The Asten Blue Twin Bunk with Trundle is a bunk bed that evolves as your kids get older. Bunk beds are always practical – even more so if they evolve as your kids get older! You can take apart the top bunk on this set and use the lower one as a single bed. It’s ideal for the day your children are ready to have separate rooms. If you need more storage, this bed can also be converted into three large drawers: all you have to do is replace the mattress with removable dividers. Available for Online Purchase Only. Assembly required. This product ships direct from the manufacturer, so RC Willey Delivery is not available.
