Staircase bunk beds are some of the sturdiest and most feature-packed kids’ and space-saving beds you can buy, but that extra construction — built-in stair treads, storage drawers, side rails, guardrails, and multiple ladder-style supports — also makes them more involved to take apart than a standard twin-over-twin frame. Whether you’re moving in 2026, switching bedrooms, converting a bunk to two separate beds, or just doing seasonal cleaning underneath, having a clear disassembly plan saves you stripped screws, scratched walls, and a pile of unlabeled bolts. This guide walks through the full process, from prep to hardware storage, based on the way most staircase bunk beds (wood or metal) are actually engineered.
Before You Start: Safety and Prep
Bunk beds with stairs are heavier and more awkward than they look, mostly because the staircase unit itself is often a solid, boxed structure rather than a lightweight ladder. Plan for at least two people for the entire job, and three if the top bunk mattress and frame need to come down a hallway or stairwell.
- Clear the mattresses first. Remove both mattresses and bedding before touching any hardware — this gives you full visibility of the frame joints and prevents a mattress from sliding off mid-disassembly.
- Photograph the assembly. Before removing anything, take photos of each corner, the staircase attachment points, and the guardrail brackets. Manufacturer manuals get lost, and a photo reference is faster than hunting online for a PDF.
- Gather the right tools. Most staircase bunk beds use a mix of Allen (hex) keys, a Phillips screwdriver, and sometimes a socket wrench for cam-lock or bolt-and-barrel connectors. An electric drill with the correct bit speeds things up enormously and reduces stripped screw heads.
- Clear the surrounding space. Staircase units are often attached to one long side of the bed and stick out further than a ladder would. Give yourself at least 3 feet of clearance on that side to maneuver the panel out.
Step 1: Remove the Guardrails
Guardrails on the top bunk are almost always attached with bolts through pre-drilled holes into the headboard and footboard posts, sometimes reinforced with a cam-lock nut on the inside. Loosen and fully remove these bolts (don’t just loosen — a partially attached guardrail can swing and pinch fingers) and set the rail aside. If your bunk has rails on both the outer and staircase side, remove the staircase-side rail last, since it may double as a stabilizing brace for the staircase attachment.
Step 2: Detach the Staircase Unit
This is the step that differs most from a standard ladder-bunk teardown. Staircase units are typically attached in two or three places:
- Bolts or brackets connecting the top of the staircase frame to the top bunk’s footboard or side rail.
- Bolts or brackets connecting the base of the staircase to the bottom bunk’s footboard.
- On models with storage drawers built into the stairs, additional screws may anchor the drawer unit’s back panel to the wall-facing side rail for stability.
Support the staircase with one person while the other removes fasteners — these units can weigh 40-70 lbs on wood models and will tip forward once the last bolt is out. Set the staircase down flat rather than leaning it, since leaning puts stress on drawer joints if it has built-in storage.
Step 3: Separate the Top Bunk From the Bottom Bunk
With the staircase and guardrails clear, you’ll be left with the two bed levels connected by the four corner support posts. These posts are usually joined with bolt-and-barrel connectors or cam locks at each corner, sometimes hidden under decorative caps that pop off with a flathead screwdriver.
- Remove the top bunk’s mattress support slats or metal deck first — this significantly lightens the top frame before you disconnect the corner posts.
- Work corner by corner, loosening but not fully removing all four connectors before pulling any single corner apart, so the frame doesn’t rack or bind.
- Once all four corners are loose, lift the top bunk frame straight up and off the lower posts with a helper on each end. On wood bunks, the posts can be a tight friction fit even after bolts are removed, so a gentle rocking motion (not prying) helps release them.
Step 4: Disassemble the Bottom Bunk and Headboard/Footboard
The bottom bunk breaks down like a standard bed frame: side rails detach from the headboard and footboard via bolts, cam locks, or hook-style rail brackets, and the mattress support slats lift out separately. If your model has built-in under-bed storage drawers, slide these out and remove them before detaching the side rails, since the drawer glides are often screwed directly into the rail.
Step 5: Organize Hardware and Panels
This is the step people skip and regret. Bag hardware by section (staircase bolts, guardrail bolts, corner connectors, slat screws) and label each bag with masking tape. Tape smaller bags to the inside of the largest flat panel (usually the headboard) so nothing gets lost in a move. Stack flat panels — headboard, footboard, guardrails, staircase side panels — vertically against a wall rather than laying them flat, which reduces the chance of warping or cracking on wood models.
Metal vs. Wood Staircase Bunks: What Changes
Metal staircase bunk frames (less common than wood, but sold by brands like Zinus and Novilla in convertible configurations) use welded steel staircase units that typically bolt to the frame at just two points rather than three, making them slightly faster to remove, though heavier per panel to carry. Wood units, common from brands like Max & Lily, Storkcraft, and Harper & Bright Designs, usually have more fasteners but break down into lighter individual pieces, which is easier on stairwells and doorways during a move.
| Task | Wood Staircase Bunk | Metal Staircase Bunk |
|---|---|---|
| Typical fastener type | Bolt-and-barrel, cam-lock | Hex bolts into welded brackets |
| Staircase attachment points | 2-3 (plus drawer back panel if storage-equipped) | 2 |
| Heaviest single piece | Staircase unit w/ drawers (40-70 lbs) | Bottom bunk frame w/ welded rails (50-80 lbs) |
| Recommended crew size | 2 people | 2-3 people |
| Common trouble spot | Stripped cam-lock screws | Rusted or over-torqued hex bolts |
Common Mistakes to Avoid
- Removing bolts in the wrong order. Always take the top bunk apart before touching the bottom bunk’s structural rails — the top frame’s weight can shift onto the lower rails and make them harder to release if done in reverse.
- Forcing stuck cam locks. If a cam-lock nut won’t turn, check that the connecting bolt is fully seated first; forcing a stuck cam lock is the most common cause of stripped fittings on wood bunks.
- Losing track of which slats go where. Number the mattress support slats with painter’s tape as you remove them if your model uses a stepped or angled slat pattern rather than uniform boards.
- Not checking local moving regulations for stairwells. A staircase unit’s width can exceed some apartment stairwell turns; measure the widest single panel against your stairwell before disassembly day if you’re moving between floors.
Once fully disassembled, most staircase bunk beds break down into 6-10 manageable pieces plus 3-4 hardware bags — comfortably transportable by two people without professional movers, provided you’ve kept the fasteners organized and photographed the original assembly for reference during reassembly.

Do I need to remove the mattress before taking apart a staircase bunk bed?
Yes, always remove both mattresses first. It gives you clear access to every bolt and connector and prevents the mattress from sliding or falling as you loosen the frame. How many people do I need to disassemble a bunk bed with stairs?
Plan for at least two people throughout, and a third when moving the staircase unit or top bunk frame, since these can weigh 40-80 lbs and are awkward to carry alone. What tools do I need to take apart a staircase bunk bed?
Most models require a Phillips screwdriver, an Allen/hex key set (often included with the original bed), and sometimes a socket wrench for cam-lock connectors. A cordless drill with the matching bit speeds up the job significantly. Do I need to remove the staircase before separating the top and bottom bunks?
Yes. The staircase is usually bolted to both the top and bottom bunk footboards, so it needs to come off before you can lift the top bunk frame free of the lower support posts. What’s the best way to keep track of all the screws and bolts?
Bag hardware by section — staircase, guardrails, corner connectors, slats — and label each bag with tape. Taping the bags to the inside of a large flat panel like the headboard keeps everything together during a move. Can I take apart a bunk bed with stairs by myself?
It’s possible for the smaller panels, but the staircase unit and top bunk frame are heavy and awkward for one person. Two people significantly reduce the risk of dropped panels or wall damage. Will my staircase bunk bed fit through a narrow stairwell once disassembled?
Usually yes, since the largest single piece is typically the staircase unit or bottom bunk frame. Measure your widest panel against your stairwell’s turn radius before moving day to be safe. What should I do if a bolt or cam lock is stuck?
