### ⭐⭐⭐⭐⭐ Better than stock!
*by N***N on October 21, 2024*

I've had two of these chairs in the past and both had the same issue. This chair was given to me by the company to promote and it's one of their more expensive lines. Sadly it's in generic red and not purple loke my last one that was their base line. But the both has the same problem the lift went out. So the chair it's self is very comfortable and this one has the Bluetooth speakers in it so I be damned if I was gonna throw out a FREE BLUETOOTH ENABLED CHAIR. If I get another chair by then I am definitely going to be buying this along side it to use instead of the stock cylinder give. The old one was a pain to get out but easy to install the new one once it was out in. I can definitely tell a difference because this one is def more study than the original one.
