Lost your furniture manual? How to assemble it anyway

Threw out the box or can't find the booklet? Here's how to find a replacement manual, identify the hardware, and assemble flat-pack furniture even with no instructions.

Losing the manual feels like a dead end, but you almost always have more options than you think. Here's the order to try them in.

1. Find the original manual online

  • Search the brand + the model name/number printed on a sticker (often under the furniture or inside a drawer).
  • IKEA: every product page has a downloadable PDF manual under 'Assembly and documents'.
  • Wayfair, Amazon, and most big retailers keep PDF manuals on the product listing.
  • ManualsLib and similar sites host scanned manuals for thousands of products.

2. If you only have a photo or a partial manual

Even a few photographed pages — blurry, out of order, or purely diagrams — can be turned into clear steps. Upload them to ManualAI and it will work out the order, track the parts across pages, and write plain-English instructions. This is the fastest route when the official PDF doesn't exist or is missing pages.

3. Assemble from the hardware itself

No manual at all? You can often reverse-engineer the build:

  1. 1Sort the hardware by type and count each kind (long bolts, short bolts, cam locks, dowels, screws).
  2. 2Dry-fit the big panels first to understand the basic shape — base, sides, back, top.
  3. 3Dowels and cam locks almost always join the main structural panels; small screws usually attach the back panel and fittings last.
  4. 4Attach the back panel near the end — it squares everything up.
  5. 5Save drawer fronts, handles and feet for the final steps.
💡 Take a photo of the furniture at each stage. If you have to backtrack, you'll know exactly how it went together — and you'll have your own 'manual' for next time.

4. Don't force anything

If a part won't seat, check its orientation (flip it) before assuming it's wrong. Flat-pack panels are often near-symmetrical with the holes in slightly different spots. Forcing a panel cracks the board.

When you're ready, the quickest path from 'no instructions' to a finished build is to photograph whatever you have and let ManualAI decode it. The first few decodes are free.
