BackEase is a one-piece ergonomic seat cushion with an integrated lumbar backrest. Unlike regular cushions that only support your seat, BackEase supports both your tailbone and lower back in one connected piece — no sliding, no adjusting.

Regular cushions only lift your seat. BackEase adds an integrated lumbar backrest, a hollow coccyx cutout (zero tailbone pressure), and high-density slow-rebound memory foam rated for 8+ hours. Most $20 cushions are flat within 2 weeks. BackEase is built to last 12+ months.

17.3″ × 16.5″ × 12.6″ (44 × 42 × 32 cm). It fits standard office chairs, car seats, truck seats, and most home chairs. Note: may not fit bucket sport seats with very high side bolsters.

BackEase fits most standard seats — sedans, SUVs, trucks, office chairs, gaming chairs, dining chairs. It's designed for universal use. If your seat has very narrow or deep bucket bolsters, measure before ordering.

The cover zips off and is machine-washable (40°C / 104°F max, gentle cycle). The memory foam core should not be soaked — spot clean with a damp cloth only. Air dry completely before reattaching the cover.
