## Questions & Answers

**Q: What is the maximum weight allowance per person**
A: I don’t know the answer but I have had this chair a couple of years and I weigh 270 lbs. I’m in it 6 to 8 hrs a day 5 days a week. It shows no wear. It is the most comfortable desk chair that I have ever owned.

**Q: Is there a warranty?  Can I return the chair if I don't like it?**
A: Yes at least through Amazon. But it is a huge box and a serious pain to return. My box was all beat up when it arrived and would have required a lot of tape to send back. I just kept it and use a big pillow to support my back when I use the chair. It is not an engineering marvel. The arm rests are so cheap. I should have bought a standard Arron chair. It looks good but it doesn’t feel good.

**Q: Anywhere I can try the chair?**
A: You can see it at Relax the Back stores.

**Q: Does this come with the 15 year X-chair warranty?**
A: X-Chair warrants this product for a period of 15 years, subject to the following exceptions:
All moving parts and materials are warranted for 5 years. During this time, X-Chair™ will provide replacement parts for any damage that is due to defect in material or workmanship. For the first 2 years, X-Chair™ will bear the entire cost of replacement parts and shipping. For the next 3 years, X-Chair™ will bear the cost of the replacement parts, but the customer will be liable for the cost of shipping.

All non-moving metal components of the chair are warranted for an additional 10 years (for a total of 15 years).

The customer must provide appropriate pictures of their damaged product if requested.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for my wife’s back
*by H***H on April 26, 2025*

My wife has been suffering from back pain so she wanted a more ergonomic chair and this chair was recommended by her PT therapist. The chair is very easy to put together, the adjustment is easy and now that we have it set up it fits her perfectly.I read several of the reviews on Amazon and was a bit concerned, but glad we bought. It took several days to get the seat, back, height, head rest, and arm rests perfect for her. I recommend patience and use the adjustments to get the chair just right for yourself before posting a bad review. My wife loves the chair and her back is doing much better since we got it. She sits in the chair 9-10 hours per day.

### ⭐⭐⭐⭐⭐ Worth the money
*by R***I on May 27, 2025*

Easy assembly - solid chair

### ⭐⭐⭐⭐⭐ Great Chair
*by A***I on September 24, 2024*

UPDATE AFTER 3 MONTHS OF USE: ZOMG this is the best office chair ever made. All criticisms withdrawn, all praise to X-Chair. I have a bulged disc in my back and this is the only office chair that has ever made long sits comfortable.This chair is pretty great. Assembly is pretty simple, and it is the most comfortable office chair I have ever experienced. The leather is a nice touch, and the back support is great for me, since I have back issues. The one problem I experienced was that the instructions about how you adjust the chair appear to be outdated, or from a different model, since they refer to levers that my chair does not have. Fortunately, the chair pretty much came properly adjusted for me, so I don't really need to know how to adjust it. It would still be nice to know what controls do what however. The best feature of this chair is the infinite recline. I need an office chair that can be set so that the back is pretty much at a perfect right 90 degree angle with the seat and perpendicular to the floor. I find that most chairs have the back tilted 10 or 15 degrees back, in which case I find myself hunching forwards without any back support. The X-Chair's back starts out pretty much at a 90 degree angle to the seat, and then moves back as you apply force. I have the resistance set to very high, so that I have to apply force with my feet to tilt back, which is exactly what I wanted—a back that is straight and supportive unless I use my feet to force it into recline. In recline, with the tension set right, my weight is perfectly counterbalanced, and I float mid-recline. The lumbar support on the highest setting works great for me.
