Outdoor cushions are made to handle sun and the odd shower, but very few are made to sit in rain for days. Most listings say water resistant rather than waterproof, and several makers tell you directly to bring cushions in during heavy rain.

This guide covers what rain does to cushions, when to bring them in, how to store them, and how to keep them in place in wind. For storage products, see Best Outdoor Cushion Storage Bags.

What Happens When Cushions Get Wet

Water-resistant fabric sheds light rain, but water can get in through seams, zippers and ties. Once foam or fiberfill is soaked, it can take a long time to dry, and a cushion that stays damp invites mildew and odors.

Quick-dry foam and open-weave fabrics help water drain out, but even those cushions last longer when they are kept dry.

Overnight and Light Rain

Leaving cushions out on a dry night is usually fine, though dew can dampen them. After a light shower, stand cushions on edge so water drains, and let them dry in sun and breeze before sitting on them.

Heavy Rain and Storms

Bring cushions in or store them before heavy rain, storms and long wet spells. Several makers in our guides, including Comcaver, Codi and STAYDEN, say to bring their cushions indoors in heavy rain, and others note their cushions are not waterproof.

Keeping Cushions in Place

  • Use every tie the cushion comes with, and tie them around a solid part of the frame.
  • Choose cushions with a non-slip backing for smooth metal and resin furniture.
  • On sloped seats such as Adirondack chairs, look for a strap that wraps over the top of the back.
  • Store loose cushions before strong wind. Ties reduce sliding, but they are not made to hold a cushion in a storm.

See Best Adirondack Chair Cushions for cushions with multi-point fastening.

Storing Cushions

  • Make sure cushions are completely dry first.
  • Store them off the ground, in a garage, shed, deck box or storage bag.
  • Do not wrap damp cushions in plastic.
  • For long winter storage, store cushions flat or on edge rather than crushed under heavy items.

FAQ

Can outdoor cushions get wet?

They can handle splashes and light rain if the maker says so, but most should not stay soaked. Dry them fully afterward.

Should I bring cushions in every night?

Not necessarily on dry nights. Bring them in when rain, storms or wind are forecast.

Can I store cushions in a deck box all winter?

Yes, if they are fully dry and the box keeps water out. Check for leaks and condensation from time to time.

The Bottom Line

Outdoor cushions can stay out in dry weather and survive the odd shower, but they last much longer when you bring them in for heavy rain, wind and winter. Dry them fully before storage, keep them off the ground, and use ties and non-slip backing to keep them in place day to day.
