## Questions & Answers

**Q: Benefits of a back cushion?**
A: Back support pillows help bridge the gap between the comfort and support your current chair lacks. Our back cushion contours around the natural curve of your spine to lessen discomfort, improve your sitting posture, and reduce sitting fatigue.

**Q: What are the benefits of using a seat cushion?**
A: Sitting for long periods of time can cause discomfort in the back, hips, and coccyx. Without proper cushioning, that discomfort becomes more agitated. Adding a chair pad to your office accessories lineup helps take the pressure off your lower body.

**Q: How to apply this back cushion?**
A: Our lumbar support cushion can be placed anywhere on your chair to support your upper, middle, or lower back. Dual adjustable straps ensure it stays in place, even if you shift about. Fits virtually any chair with a maximum width of 32” (81cm).

**Q: How to use this seat cushion?**
A: Place the seat cushion on any chair with the Everlasting Comfort logo at the front and the U-shaped coccyx cutout at the back.

**Q: Can you wash the cushions?**
A: Yes, our cushions feature a removable cover that’s easy to clean and keep fresh. Simply unzip the cover from the memory foam, and toss cover into the wash on the gentle cycle. Tumble dry with low heat for best results.
