- Choices: Available in natural, white or chestnut finish; and with slat, panel or curve bed end style.
We swapped the ladder for a staircase on our classic twin over full bunk bed then added 4 more inches in length. The ‘SUMO XL’ combines full XL bed on the bottom with a twin XL up top.
Staircase makes it easy for kids to climb up top and plenty sturdy enough for grown ups as well. Each step has a deep drawer, providing built in storage to help keep rooms tidy.
Perfect for a growing older child in a shared bedroom. Parents appreciate the extra room to stretch out at story time. It also provides comfortable sleeping quarters for adult overnight guests.
Pairs perfectly with matching trundle bed to sleep one more, or opt to add underbed drawers for extra storage. Requires Twin XL and Full XL size mattresses.
Patented rock lock system connects the beds securely and prevents wiggling. Simply “unlock” and separate for two traditional beds, or convert into another style entirely.
Overall: L: 104.75" x D: 57.5" x H: 66.25"
NOTE: Staircase is reversible and can be positioned on either side of the bed.
Height is measured from the floor to the top of the guardrail.
Guardrail height: 16" (measured from the surface of the slats to the top of the guardrail)
Mattress support slats are spaced 2.75" apart.
Underbed height: 37" (measured from the slats of the lower bed to the slats of the upper bed)

This bunk is exactly what we were looking for - plenty of space at the bottom for sleepovers, or we use it as a "couch" for story-time sometimes, so everyone is comfortable. We added a tent to the top so our girl still has a princess feel when she goes to bed (and we will probably remove this when she gets older).What's also nice is that the bottom bunk is comfortable to stand on when we kiss her goodnight! Love the staircase too, great extra storage and feels really sturdy and safe. We are very happy with our purchase.
