Understand the cover
Look for a fabric specification rather than vague wording. Ask about UV resistance, water repellency, mildew resistance, colourfastness, and cleaning instructions. Water-repellent is not the same as waterproof.
Removable covers make some cleaning easier, but removing a tight cover can be difficult. Check zips, seam construction, and whether replacement covers are sold.
Check the fill and drainage
Quick-dry foam and ventilated fill can release water faster than dense indoor foam, but they still need airflow. A waterproof outer cover may trap moisture if water enters through seams or zips.
Frames and cushion platforms should allow water to escape. Avoid leaving wet cushions stacked together.
Match colour to exposure and care
Very dark and very bright colours may show fading differently; pale colours can reveal dirt. Pattern can hide marks but complicate replacement matching.
Choose a colour you can maintain with the cleaning method the manufacturer permits.
Store cushions dry
Before storage, clean and dry cushions fully. Use a ventilated, dry location and inspect periodically. Storage bags and boxes need airflow unless they are designed for sealed storage of completely dry items.
Do not assume a deck box will keep contents dry in every storm. Test and inspect it.
Frequently asked questions
Are outdoor cushions waterproof?
Many are water-resistant or water-repellent rather than waterproof. Check the cover, seams, zip, fill, and manufacturer’s care instructions.
What helps cushions dry faster?
Ventilated fill, drainage paths, airflow, standing cushions on edge, and moving them to a dry covered area can help.
Can outdoor cushion covers go in a washing machine?
Only when the care label permits it. Some finishes can be damaged by machine washing, heat, bleach, or strong detergent.
