## Questions & Answers

**Q: I'd also like to know what the weight limit is...could you please tell us?**
A: I just looked up the SKU-S6112-HD & the weight limit is posted as 500lbs on 4 different websites.

**Q: Looking for something with at least a 200 lb weight limit.**
A: My weight is 325, I bought this and it seems to be doing the job.

**Q: I have a dxracer (specifically it's an oh/rb1/ne) and i was wondering if this will fit in the chair? the current gaslift does not go high enough.**
A: I put this one in my dxracer king series chair, and it fit just fine (and works way better). There are only two types of bases for the dxracer chairs, and both seem to take the same (standard) gas lift, so it should work for yours.

**Q: Will this fit an aeron chair?**
A: Fits most chairs with 1-2" added height.  I used it in a Hon Executive High Back Chair, 5400 Series, For Big And Tall
