What you need

In the box already: Plastic connectors or cam locks · Panels · Mallet · Anti-tip strap · Fabric bins

Before you open anything

  • Work out which type you have. If it came with plastic X-shaped connectors it is the tool-free kind. If it came with an Allen key and metal discs, follow the cam-lock box pattern instead.
  • Build it flat on the floor, then stand it up. Building a grid standing up is a losing battle.
  • Decide now whether it goes against a wall. Tall cube units must be anchored.

Please don't skip these

  • Cube units are light and children love climbing them. Anchor anything taller than two cubes high.
  • Never stack two separate cube units on top of each other unless they are designed to connect.

The whole thing, step by step

9 steps
  1. Identify which system you have

    Plastic X or T-shaped connectors means the tool-free kind. Metal discs and an Allen key means it is really a cam-lock box in a grid shape.

    • Look in the hardware bag
    • Plastic connectors: carry on with this guide
    • Cam locks and Allen key: the cam-lock box guide is the one you want
    Tip. A few units are a hybrid, with plastic connectors and screws for the back. Read the parts list.
  2. Lay out the grid flat, dry, before connecting

    Put the panels on the floor in the shape of the finished grid without connecting anything. You will instantly see how it goes together.

    • Outer panels around the edge
    • Inner divider panels where the cubes split
    • Compare against the manual picture
    Tip. Dry-laying the whole thing first takes two minutes and prevents the classic problem of discovering you are a divider short at the far corner.
  3. Start with one corner

    Push a corner connector onto the edge of one panel, then push the second panel into the other side of the connector. Firm, straight pressure.

    • Connector onto panel one, straight on, not angled
    • Panel two into the other slot
    • Press until it bottoms out
    Watch out. Angled pressure cracks plastic connectors. If it resists, you are not square to the slot.
  4. Build out one row at a time

    Work along one row completely before starting the next. Each new panel adds stiffness, so the grid gets easier to handle as you go.

    • Complete the bottom row first
    • Then add the uprights for the next row
    • Then the next horizontal row
    Tip. Work on the floor with the back of the unit facing down. Gravity holds everything in place for you.
  5. Seat every connector fully

    Go back over every joint and tap it home with the mallet or the heel of your hand. Half-seated connectors are why these units feel flimsy.

    • Tap each joint, gently
    • Look for any gap between panel and connector
    • The grid should feel rigid, not springy
    Watch out. If you can see daylight at a joint, it is not seated. That one joint will be the one that fails.
  6. Square the grid and fit the back if there is one

    Measure the diagonals of the outer rectangle and push until they match. Then fit any back panel, which locks that shape in.

    • Diagonals equal
    • Back panel on, printed side out
    • Nails or screws at corners first, then around
    Tip. Many cube units have no back at all. Those rely on being anchored to the wall for rigidity, which makes the next step more important, not less.
  7. Stand it up and anchor it

    Stand it up where it lives, then strap it to the wall. A cube unit full of books is heavy and has almost no base depth to resist tipping.

    • Stand up with help if it is wide
    • Find a stud or use a proper anchor
    • Strap at the top, snug
    Watch out. Cube organizers in children's rooms are among the most commonly tipped furniture there is. They are light, grippy, and exactly the right shape to climb.
  8. Drop in the bins and load it

    Assemble any fabric bins by folding their stiffener panels in, then slide them into the cubes. Heavy things at the bottom.

    • Fabric bins: slide the cardboard stiffeners into their fabric sleeves
    • Bins into the lower cubes for heavy items
    • Keep the top row light
    Tip. If a bin is a tight fit, squeeze it slightly as it goes in. They are usually cut a hair generous on purpose.
  9. Final push test

    Push the top of the unit firmly. With the strap on it should barely move. Any flex means a connector somewhere is not seated.

    • Push at the top corner
    • Listen for clicks or creaks
    • Re-tap any joint that moves
    Tip. Check the strap again after a month. Drywall anchors can settle a little under constant tension.

If something has gone wrong

A plastic connector cracked

They are sold separately by every manufacturer and in generic multi-packs. Order spares — if one cracked, the unit is probably under some stress, so check the grid is square.

The whole unit racks and leans like a parallelogram

That is normal for a backless cube unit and exactly what the wall strap is for. Square it, then anchor it. Adding a back panel of thin hardboard also works very well.

The panels will not push into the connectors

You are going in at an angle, or there is a burr in the slot. Line it up dead square and press with your palm, not your fingertips. Check the slot for flashing you can trim with a knife.

A cube is slightly too small for my bins

Measure the cube opening and buy bins to match. Cube sizes vary between brands even though they look standard — a common size is around thirteen inches, but not universally.

Can I stack two units?

Only if the manufacturer says so and only when both are anchored to the wall. An unanchored stack is the least stable furniture arrangement in a house.

Words you will see in the manual

connector
A plastic joining piece on tool-free furniture. Press it on square, fully home. Angled pressure cracks it.
square
Describes a frame whose corners are true right angles. You check it by measuring both diagonals: if the two numbers match, it is square.
anti tip
A strap or bracket that ties furniture to the wall so it cannot fall forward. Required on anything taller than it is wide, and on every dresser in a home with children.
stud
The vertical timber inside a wall, usually every 16 or 24 inches. It is what you screw an anti-tip bracket into. Drywall alone will not hold furniture.
