Garden Bench Cushions: How to Choose the Right One for UK Weather
A garden bench is only as comfortable as the cushion on it. But with the UK's unpredictable weather — sunshine one hour, rain the next — choosing the right outdoor cushion takes a little more thought than picking one for indoors. This guide covers everything you need to know.
Why UK Weather Makes Outdoor Cushions Different
Unlike warmer climates where outdoor furniture stays dry most of the year, UK gardens face rain, humidity, morning dew, and the occasional surprise downpour. A cushion that isn't built for these conditions will quickly become waterlogged, mouldy, and uncomfortable. The right cushion needs to handle moisture, dry quickly, and hold its shape season after season.
What to Look for in a Garden Bench Cushion
1. Waterproof Cover
This is non-negotiable for UK gardens. A waterproof outer cover prevents rain from soaking into the foam, which would cause it to become heavy, cold, and eventually mouldy. Look for covers with sealed seams or water-resistant fabric treatments for the best protection.
2. High-Density Foam
Outdoor cushions take more punishment than indoor ones — UV exposure, temperature changes, and repeated wetting and drying all degrade foam over time. High-density foam resists compression and holds its shape far longer than low-density alternatives, making it worth the investment for garden furniture you use regularly.
3. Removable, Washable Cover
Even with a waterproof cover, garden cushions get dirty — pollen, bird droppings, sunscreen, and general outdoor grime all take their toll. A removable, machine-washable cover makes it easy to keep your cushions looking fresh without replacing them entirely.
4. The Right Size
Garden bench cushions come in sizes to fit 2, 3, and 4-seater benches. Measure your bench seat carefully — length, width, and the depth you'd like — before buying. A cushion that's too small looks untidy; one that's too large won't sit properly.
5. Thickness
For a garden bench, a cushion thickness of 5–8cm is typically ideal. Thinner cushions don't provide enough comfort for extended sitting; thicker ones can make the bench feel unstable. If you're using the bench for dining, a firmer, thinner cushion works well. For relaxed lounging, go thicker and softer.
Should You Bring Cushions Inside When It Rains?
Even with waterproof covers, it's good practice to store cushions indoors or in a garden storage box during prolonged rain or when not in use. This extends their life significantly and keeps them looking better for longer. If you'd rather leave them out, look for cushions with fully sealed waterproof covers rather than just water-resistant ones.
How to Clean Garden Bench Cushions
- Remove the cover and machine wash according to the label instructions
- Wipe the foam with a damp cloth if needed and allow to air dry fully before replacing the cover
- Never put foam in a washing machine or tumble dryer
- Store clean and dry at the end of the season to prevent mould
