Picture a small room on a winter evening. Up top, a bed with fairy lights along the rail and a book waiting on the pillow. Underneath, a warm desk lamp, your laptop and a plant in the pallet shelf beside it.

Work ends, you climb six steps, and you're in bed without ever leaving the room. A friend visiting for the first time stops in the doorway: "Wait, where's the bed?"

That's the pallet loft bed from our video: a twin bed on a deck of white pallets, held by two pallet towers, two posts and a beam, with a desk underneath. You can build it yourself in a weekend, plus a night for the paint to dry. With free pallets, the lumber, hardware and ladder come to about $210 to $340, not counting the mattress and the desk.

When a pallet loft video goes around, the comments ask the same things. What holds the middle up? Are those screws going into anything? What stops you rolling off? Every answer is below, with 7 steps and a picture for each, plus the five mistakes that make a loft bed wobble, sag or let someone fall.

At a glance

  • Time: a weekend, plus a night for the paint to dry
  • Skill: intermediate. You find studs, drive long screws into them and lift pallets overhead with a helper.
  • Cost: about $210 to $340 with free pallets, not counting the mattress and the desk
  • Best time to build: now. On Pinterest, searches for a loft bed with a desk run highest in early October, right when the room has to work as an office all winter.

Start with a sturdy ladder that bolts on

You climb it every night, often half asleep. A ladder fixed to the beam with brackets is what makes those six steps safe.

How the Pallet Loft Bed Holds Up

Diagram of the pallet loft bed: a side cut with the deck pallet on a wall ledger and a front beam, the rail height and the ceiling check, and the loft from the front with towers, posts, ladder and desk.

Nothing hangs in the middle. The deck pallets span from the back wall to a beam at the front, so every pallet is held at both ends.

  1. Two pallets stand on each side wall, one on top of the other, lag-screwed into the wall studs. They're the side towers.
  2. A 2×4 ledger is screwed into the back-wall studs, and a 2×6 beam joins two 4×4 posts at the front, both at the tower height.
  3. Two pallets lie front to back on the ledger, the beam and the tower tops, screwed down. A twin mattress fits on top.

In the original video, the deck seems to float with little under it. Here every load path goes to a stud, a post or the floor, and the rails follow the federal bunk bed rules.

What You Need, and What It Costs

A woman tilting a white pallet up against a wall, with painted pallets, two 4x4 posts and lumber on the floor of an empty room.
  • Wood pallets, six matching ones, about 48 by 40 inches, stamped HT.
  • 4×4 posts, two 8-foot posts, for the front corners.
  • Post bases, two steel brackets for 4×4 posts.
  • 2×6 board, one 8-foot board, for the front beam.
  • 2×4 board, one 8-foot board, for the back ledger.
  • Lag screws and washers, 3/8 inch by 4 inches, for the towers and the ledger.
  • Structural wood screws, 3 inches, and four mending plates for the tower joints.
  • 1×4 boards, three 8-foot boards for the guardrails (five if children will sleep up there).
  • Loft ladder, a sturdy wooden one about 6 feet long, with mounting brackets.
  • White paint, one gallon, with a roller and a brush.
  • Tools: stud finder, drill and impact driver, level, tape measure, saw, step stool, a helper, work gloves and safety glasses.

What it costs: about $210 to $340 in all with free pallets, not counting the mattress, the desk and tools. That's with prices we found at US stores on October 21, 2026. The posts, beam and ledger are about $45 to $73 and the post bases about $27 to $29. The screws and plates are about $30 to $45 and the rail boards about $30 to $42. The ladder is about $50 to $100 and the paint about $30 to $50.

Two buying tips:

  1. Pick six pallets of the same size and type, all stamped HT. Mixed pallets leave a deck with steps and gaps under the mattress.
  2. Check the ladder's length against your deck height before you buy it. It should reach the deck at a comfortable slope, not stand straight up.

Step 1: Measure the Room, Then Paint the Pallets

Close-up of a brush laying white paint onto the bare boards of a wooden pallet.
  1. Measure from the floor to the ceiling.
  2. Sit on the floor against a wall and mark the wall just above your head. That's the room you need above the mattress to sit up.
  3. Add up: about 86 inches to the deck top in this build, plus your mattress, plus that sitting height. If it's more than your ceiling, this loft isn't for this room.
  4. Sand the pallets, paint them white, two coats, and let them dry overnight.

Watch out: do the math before you buy anything. The video's room has a high ceiling; in a standard 8-foot room, a deck this high leaves too little space above the mattress to sit up.

Step 2: Screw the Side Towers Into the Wall Studs

Close-up of an impact driver sinking a lag screw through a white pallet block into the wall, a little sawdust below.
  1. Find the studs on both side walls and mark them.
  2. Stand the first pallet against a side wall, long edge on the floor, and drive lag screws through its blocks into the studs.
  3. With a helper, stand the second pallet on top, and join the two with mending plates.
  4. Lag-screw the top pallet into the studs too, then build the other tower the same way.

Watch out: every lag screw goes into a stud. Drywall alone pulls out under a sleeping adult, and this is the part that holds the whole bed.

Step 3: Stand the Posts and Screw Down Their Bases

Close-up of a driver sinking a screw through a steel post base into the floor at the foot of a 4x4 post.
  1. Set the two 4×4 posts at the front corners, in line with the tower fronts.
  2. Fix each post into a steel post base, and screw the base down to the floor.
  3. Check each post with the level on two sides.

Watch out: fix the post bases to something solid. On a wood floor, screw into the subfloor; on concrete, use concrete anchors made for the bracket.

Step 4: Fix the Ledger and the Front Beam

A woman on a step stool screwing a 2x6 beam across the two front posts, at the height of the pallet towers.
  1. Screw the 2×4 ledger across the back wall, level with the tower tops, with a lag screw into every stud.
  2. Screw the 2×6 beam across the inner faces of the two posts, at the same height.
  3. Check that the ledger, the beam and both tower tops are level with each other.

Watch out: set all four supports at exactly the same height. If one is low, the deck rocks and the screws work loose over time.

Step 5: Lay the Deck Pallets and Screw Them Down

A woman on a step stool pushing the second white pallet onto the beam and the right tower to finish the loft deck.
  1. With a helper on a second stool, slide the first deck pallet onto the beam, the ledger and the left tower top.
  2. Slide the second one in beside it, over the right tower.
  3. Screw each pallet down into the beam, the ledger and the towers with 3-inch screws.

Watch out: lift overhead only with a helper. A pallet slipping off a stool at shoulder height is the most dangerous moment of the whole build.

Step 6: Add the Guardrails and Fix the Ladder

A woman fixing a white wooden ladder to the front beam of the loft bed, the top rail already in place.
  1. Screw a 1×4 rail between the post tops, so its top sits at least 5 inches above your mattress.
  2. If children will sleep up there, add boards below it, so no gap down to the deck is wider than 3 1/2 inches with the mattress off.
  3. Fix a rail along the wall side too, and bolt the ladder to the beam with its brackets.

Watch out: follow the bunk bed rules, even though you built it. The CPSC's bunk bed requirements call for a guardrail on each side, the wall-side rail running end to end, and rail tops at least 5 inches above the mattress.

Step 7: Make the Bed and Set Up the Desk

A woman sliding a wooden desk with a monitor and lamp under the loft bed, an office chair beside it.
  1. Push a twin mattress up the ladder onto the deck, and make the bed.
  2. Slide the desk under the loft, with the chair in front.
  3. Wind battery fairy lights along the rail and put a lamp on the desk.

Watch out: use a mattress no thicker than the rails allow. A thick mattress leaves less than 5 inches of rail above it, and the rail stops doing its job.

The Mistakes That Make It Fail

People who see a pallet loft bed look for what's wrong. These five give it away fast:

  1. No room to sit up. Measure the ceiling first.
  2. Screws into drywall. Every lag screw goes into a stud.
  3. A deck held at one end. The ledger and the beam hold both ends of every pallet.
  4. One rail board with gaps below. Add a rail on the wall side, and fill the gaps if children sleep there.
  5. Lifting pallets overhead alone. Always with a helper.

Get those five right, and the loft feels as solid as the floor.

Keep the Loft Bed Solid

  • Check every lag screw and post-base screw each season, and tighten any that turned.
  • Keep fairy lights battery powered, so no cord runs up the ladder.
  • Vacuum the pallet slots under the deck, where dust collects.
  • Touch up the paint on the ladder rungs once a year.

Then switch off the desk lamp, climb the six steps, and let the next visitor ask where the bed went.

FAQ

How High Should a Loft Bed Be?

High enough for what goes under it, and low enough to sit up in bed. Add the deck, the mattress and your sitting height; it must fit under your ceiling.

Do Loft Beds Need Guardrails?

Yes. The CPSC rules for beds more than 30 inches off the floor call for a rail on each side, with the tops at least 5 inches above the mattress.

Can a Pallet Loft Bed Hold an Adult?

It can when every pallet is held at both ends and every support goes into studs, posts or the floor. Never let one hang from drywall.

What Size Mattress Fits a Pallet Loft Bed?

Two 48-by-40-inch pallets make a deck about 48 by 80 inches, which fits a twin mattress.

Are Pallets Safe to Use for a Bed?

Use pallets stamped HT, which were heat treated, and skip any stamped MB or with stains or a smell.

How Much Does a Pallet Loft Bed Cost?

About $210 to $340 with free pallets, not counting the mattress and desk, at US store prices in October 2026.
