    Sturdy seat



    Verified Purchase

    Firm sturdy seat that seems like it will last forever. I should have thought this through more. It’s not your leanback kick your feet up kind of chair, I miss that. The headrest is off centered and that is irritating. The armrests are quite comfortable and easy on the elbows. Overall a four out of five.
