Topotdor Outdoor Chair Cushions Set of 2 (Cream) – 17x16x2
These 17x16x2 inch cushions come as a pair, offering right-sized seating for most mid-sized chairs. They use a 2-inch high-density foam that delivers elastic support and comfort, designed to reduce pressure on the lower back and hips. The fabric is a 100% dope-dyed polyester that resists fading for up to 1200 hours of sunlight exposure, making them a solid outdoor option. A vacuum-packed foam insert decompresses within 24-48 hours after unboxing to regain full loft. The cushions are waterproof and stain-resistant, helping protect the foam from rain and spills. Ties secure the cushions to the chair to prevent slipping. Suitable for outdoor patios and garden furniture, they balance durability with a skin-friendly feel.

Buying Guide: Key Purchase Considerations
- Size and fit: Measure your chair seating area to ensure the cushion’s diameter and thickness match. Round and half-round styles vary; verify the exact dimensions before purchase.
- Material and fill: Memory foam and high-density foam deliver different levels of support and longevity. Velvet and corduroy fabrics offer comfort and style but may require maintenance for outdoor use.
- Outdoor durability: If cushions are used outdoors, prioritize waterproof or water-resistant fabrics, fade resistance, and internal layers designed to protect foam from moisture.
- Secure attachment: Look for ties, handles, or non-slip backs to keep cushions in place during use, preventing shift and discomfort.
- Care and maintenance: Removable, washable covers simplify cleaning and prolong cushion life. Check whether the fabric is machine washable or spot-clean only.
- Color and style: Choose colors that complement your existing furniture and decor. Neutral tones tend to coordinate easily with different settings.
- Durability and warranty: For frequent use, prioritize cushions with durable covers and robust internal supports, and consider manufacturer warranties when available.
- Indoor vs outdoor use: Indoor cushions may not be suited for rain or humidity; outdoor cushions often include protective layers to withstand weather exposure.
