What are the effects of humidity on the dimensional stability of canvas benches?

Humidity significantly impacts the dimensional stability of canvas benches, often causing warping, shrinkage, or expansion of the wooden frame. High moisture levels can weaken the canvas fabric, leading to sagging or stretching. Over time, repeated exposure to humidity may compromise the structural integrity of the bench. To mitigate these effects, choose treated or weather-resistant materials and store benches in dry conditions when not in use. Regular maintenance, such as applying protective coatings, can also prolong the lifespan of outdoor canvas benches.
