# How to Assemble a Slatted Bed Frame

> A slatted bed frame usually joins a headboard, footboard, two side rails and a row of slats. Fit side rails to the ends, add the centre rail if supplied, then clip or screw slats with even gaps. Keep gaps within mattress warranty limits — often about 7 cm. Place the mattress only when the frame feels rigid.

Structural components: headboard and footboard, side rails, centre support rail, solid or sprung slats.

## Step-by-step

1. **Ends** — stand headboard and footboard.  
2. **Side rails** — hook or bolt both rails; do not fully torque yet.  
3. **Square the frame** — measure corner-to-corner diagonals; they should match.  
4. **Centre rail** — fit if supplied; adjust the support leg to the floor.  
5. **Slats** — space evenly; secure clips or screws.  
6. **Final tighten** — work around the frame.  
7. **Mattress** — confirm [base compatibility](/care/mattress-base-compatibility).

## Sprung versus solid slats

| Slat type | Assembly note |
| --- | --- |
| Solid | Often drop into ledges or screw down |
| Sprung | Sit in flexible caps; do not over-bend to fit |

## Frequently asked questions

### Why does my new bed frame wobble?

Bolts may be unevenly tight, the frame may not be square, or a centre leg may be missing on carpet. Loosen slightly, pull the frame into square by equal diagonals, then retighten. Check all feet touch the floor.

### How far apart should bed slats be?

Follow the mattress warranty. Many foam and hybrid makers want clear gaps of about 7 cm or less. Wider gaps can void warranties and let foam sag between slats. See the slatted bases guide.
