# Is a 3 or 4 inch cushion thick enough on a hard wooden bench?

*Plywood doesn't give, so the foam does all the work. Here is the thickness table from real benches and real replies.*

Also asked as: Is 3 inch thick enough on plywood?; Kitchen nook bench cushion thickness?

> **The quick answer:** Yes, a 3 inch (7.5 cm) cushion is thick enough over a plywood kitchen nook bench, and 4 in (10 cm) is the recommendation for sitting and napping on a hard wooden or wicker base. Most customers who pick 4 in find it comfortable. For more loft, 6 or 8 in (15 or 20 cm) can be made on request at a higher price.

## Key facts

- 3 in (7.5 cm) is enough over a plywood nook bench.
- 4 in (10 cm) is recommended for daybeds and hard wooden or wicker bases.
- Most customers choose 4 in and find it comfortable.
- 6 or 8 in (15 or 20 cm) is made on request at a higher price.
- Firm 32-density foam, about 2 lb/ft³ (32 kg/m³), barely compresses, so the thickness ordered is close to the height added.

## Thickness by base and use

| Base | Main use | Thickness | Note |
|---|---|---|---|
| Plywood kitchen nook bench | Sitting at the table | 3 in (7.5 cm) | Enough, per the workshop |
| Dining bench already at seat height | Daily meals | 2-3 in (5-7.5 cm) | Firm 32-density foam barely compresses |
| Daybed, willow sofa or wicker base | Sitting and napping | 4 in (10 cm) | The recommendation; most buyers keep it |
| Wooden swing platform, 51 x 82 in (130 x 208 cm) | Lounging, with a backrest | 4 in, or 8 in (20 cm) | Quoted both ways; 8 in costs more |
| Any hard base | Extra loft | 6 or 8 in (15 or 20 cm) | On request, higher price |

## Why the nook gets 3 in and the daybed gets 4

At a table, the cushion is part of your seat height, and firm 32-density foam (about 2 lb/ft³) barely compresses. Every inch you add, you keep. That's why 3 in works over plywood, and why a bench already at seat height can drop to 2-3 in so the table height stays comfortable.

Napping is a different load case, partner. You're lying on the cushion, not perched on it, and a hard wooden or wicker base gives nothing back. That's where 4 in earns its place. Run your numbers through the [seat height calculator](https://cushionguide.com/studio/seat-height-calculator/), then read [banquette cushion thickness and table height](https://cushionguide.com/guides/banquette-cushion-thickness-table-height/).

What does your bench measure from floor to seat?

> **Tailor's margin:** On a hard wooden bench, 3 in of foam suits sitting at a table; if the bench doubles as a napping spot, go to 4 in.

> Over a plywood kitchen nook bench, a 3 in cushion is enough; for sitting and napping on hard wood or wicker, 4 in is the workshop's recommendation.

## Buyer questions

**A common question:** Is a 3 inch cushion thick enough to sit on comfortably over a plywood kitchen nook bench?

**The workshop's answer:** Yes, the workshop said 3 in would be fine over plywood. Firm foam barely compresses, so check that the table still clears your knees with 3 in added.

**A common question:** Is 4 inches enough for sitting and napping on a hard wooden or wicker base?

**The workshop's answer:** The workshop recommends 4 in, which most customers prefer and find comfortable. For a curved willow sofa base and a 51 x 82 in swing platform, it quoted 4 in as standard and 6 or 8 in as a pricier step up.

**A common question:** Is 4 inches your standard thickness for bench cushions?

**The workshop's answer:** Yes. 4 in (10 cm) is standard for bench, window seat and floor cushions, and most buyers keep it. Thicknesses from about 2 in up to 12 in are made to order; thicker than standard costs more.

## Questions buyers ask next

### Does going from 4 in to 6 or 8 in change the price?

Yes. 4 in is the standard, and 6 or 8 in is made on request at a higher price, like any thickness above standard. The quote for your exact size and thickness gives the figure.

### What foam goes inside a nook bench cushion?

Firm 32-density foam, about 2 lb/ft³ (32 kg/m³), which barely compresses when you sit. The thickness you order is close to the height you add, so check the table clearance first.

### How long does a custom nook bench cushion take?

One nook bench order like this was quoted at 5-7 days of production, then 3-5 days of delivery after dispatch. Ask for the current times with your own quote.
