Which Plywood for a Sofa, Takhat or Diwan? Thickness and Grade

Short answer: a sofa's base frame, seat base and arms in 18mm plywood, the backrest in 12mm. A takhat top in 18/19mm with support underneath every 2 ft, or 25mm plywood or block board for a big top. MR in a dry room, BWR on a ground floor.
Sofas and takhats take the most jolts
People lie quietly on a bed; on a sofa or takhat they sit, bounce and stand up, and children jump. So screw grip and strong joints matter most in their frames.
Sofa
| Part | Material | Thickness |
|---|---|---|
| Base frame (under the seat) | Plywood, full or good core | 18mm |
| Seat base (under the cushion) | Plywood | 18mm (or 12mm with strips or supports underneath) |
| Side arms | Plywood | 18mm |
| Backrest | Plywood | 12mm |
| Small inner strips | Plywood or wooden battens | 12–18mm |
- Grade: MR if the living room is dry; BWR on a ground floor or near damp.
- Don't use thin plywood (6–9mm) in the sofa's load-bearing parts; it bends over time and fails.
- Sofa legs are available at our shop too; pick them to match the frame. See furniture hardware.
Takhat
| Part | Material | Thickness |
|---|---|---|
| Top | Plywood or block board | 18/19mm, with support underneath every 2 ft |
| Frame and sides | Plywood or timber | 18mm |
| Storage bottom (if it has a box) | Plywood | 12mm |
For a takhat top of 6 x 4 ft or larger without a middle support, use 25mm plywood or block board.
Diwan (with storage)
A diwan is really a small box bed: the top and frame in 18/19mm, the bottom and partitions in 12mm. The full guide: what thickness of plywood for a bed. Sheet count: the plywood sheet calculator (bed option).
Finish
- A sofa or diwan frame is usually hidden under cushions or fabric; protect it from moisture with liner laminate or polish.
- A takhat top shows: 1mm laminate on top, liner underneath, and edge band on the edges.
