Solid Wood Bunk Beds

Every bunk bed in this collection is built on a 100% solid wood frame — kiln-dried pine from renewable Brazilian forests or plantation-grown rubberwood. Choose twin over twin, twin over full, full over full, or a twin bunk over a full-size futon, with a ladder or a staircase with built-in storage. All models include slat support, so no box spring is needed, and are independently tested to federal bunk bed safety standards.

Mattress fit matters more on a bunk bed than on any other frame. The top bunk takes a thinner mattress than the bottom so the guardrails stay well above the sleeping surface — federal standards require the top of the guardrail to sit at least 5 inches above the mattress. Check the maximum mattress thickness for each model for the top and bottom bunks; low-profile foam or hybrid mattresses are the usual choice up top.

A bunk bed can change as your family does. Depending on the model, you can add rolling storage drawers or a pull-out trundle under the lower bunk, or convert a twin over twin to a twin over full with a separate kit. Each product page lists the add-ons and kits that fit that frame.

Peppermint Staircase Bunk Bed • Twin Twin

Bunk Beds with Stairs or a Ladder

A ladder takes up the least floor space and can usually be mounted on either side of the frame. A staircase needs more room but gives wider, flatter steps and a handhold on the way up, which makes it safer for younger children than a ladder, especially coming down half-asleep. Staircases on bunk beds usually have storage built into the steps, drawers or shelves that can replace a small dresser. Ladder models can get storage too, with optional rolling drawers or a pull-out trundle under the lower bunk.

Ginger Bunk Bed • Twin Full • Trundle Bed

Twin over Twin, Twin over Full or Full over Full

Choose the layout by who will sleep on each bunk. Twin over twin takes the least floor space and suits younger siblings sharing a room. Twin over full adds a full-size lower bunk with room for an older child, a parent at bedtime or an overnight guest. Full over full gives both sleepers a full-size mattress, the practical choice for teens, adults, guest rooms and vacation homes. If you're unsure which fits your room, compare the dimensions and uses of each bunk bed size before you order. A futon bunk bed replaces the lower bed with a sofa that converts to a full-size bed, so the room works as a living space during the day.

Cinnamon Futon Bunk Bed

Sturdy Bunk Beds for Kids, Teens and Adults

A bunk bed takes more load and movement than a standard bed frame: climbing, sitting on the edge, kids getting older and heavier. Solid wood frames with bolted or mortise-and-tenon joints hold their shape under that use better than particleboard or lightweight metal, and the hardware can be re-tightened as the wood settles, which is why they hold up as bunk beds for teens as well as young kids. Keep guardrails on both long sides of the top bunk, and follow the American Academy of Pediatrics recommendation that children under 6 not sleep on the top bunk.

Frequently Asked Questions: Bunk Beds

What size mattress do I need for a bunk bed?

Most bunk beds in our collection accommodate standard twin or full mattresses depending on the configuration you choose. For the top bunk specifically, we recommend a mattress no thicker than 6 inches — this keeps the guardrail at its maximum effective height and ensures smaller children are properly protected. The lower bunk is more flexible and can typically accommodate mattresses up to 9.25 inches.

What is the difference between a ladder bunk bed and a staircase bunk bed?

A ladder bunk bed uses a compact vertical or angled ladder to access the top bunk, keeping the overall footprint of the bed smaller. A staircase bunk bed replaces the ladder with a set of built-in stairs, which provides a wider, more stable surface to step on — a meaningful difference for younger children climbing up and down at night. Staircase models do require more floor space along the side of the bed, so it is worth measuring your room before choosing.

What wood are your bunk beds made from?

Our collection includes two primary wood types. Several models are crafted from 100% solid, kiln-dried pine sustainably sourced from renewable Brazilian forests. Others are built from eco-friendly rubberwood harvested from plantation trees at the end of their latex-producing lifespans. Both are solid hardwoods — no veneers, no composites, and no formaldehyde-based glues.

Are bunk beds safe for young children?

Yes, when used correctly. All bunk beds in our collection are independently tested to meet or exceed federal safety standards. We recommend that children under six years old sleep on the lower bunk, and that guardrails are always kept in place on the top tier. Our staircase models are particularly well-suited to younger children, offering a wider and more confidence-inspiring climb than a traditional ladder.

Do your bunk beds come with slats, or do I need to buy a box spring?

None of the bunk beds in our collection require a box spring. Every model ships with everything needed to support your mattress directly — no additional foundation necessary. Simply assemble the frame, place your mattress, and the bed is ready to use.

Can I convert a twin-over-twin bunk bed into a twin-over-full later on?

Yes — every twin-over-twin bunk bed in our collection can be converted into a twin-over-full configuration down the road, so there is no need to buy a new bed as your family's needs change. A full conversion kit is available as a separate add-on and includes everything required for the upgrade: two end sections, a support beam with legs, a full-size slat kit, and all necessary hardware. Simply install the kit onto your existing frame and the lower bunk expands from a twin to a full. It is a practical investment that extends the life of your bed for years to come.

Can I add a trundle or storage drawers to a bunk bed?

Most models accept optional rolling storage drawers or a pull-out trundle under the lower bunk. The futon bunk bed is the exception: it uses its own matching drawer set and does not fit a trundle. Each product page lists the add-ons that fit that model.

Do you have full over full bunk beds?

Yes. Use the Size filter at the top of this page to see the models available in full over full, along with twin over twin and twin over full.
