Comfort is important -- very important. You may want steel or wood construction in your patio furniture for stability and longevity, but don't forget that without some homey comforts like soft, plush cushions, your outdoor furniture will go largely unused. Avoid pancake cushions. You know, those thin, puny little cushions that aren't plush or even very pliable. Opt for chubby cushions that feel light when you pick them up. Look for cushions with polyester filler, too. The more lightweight and springy the filler is, the more quickly it will dry out after exposure to moisture. That means it will resist mold and mildew and stay comfortable and sweet smelling longer.
