One of my rocker glider's ended up buckling due to a screw in the glider base getting stripped, I'm not certain but it is likely my fault for assembling them with a 1/4" impact driver while drinking cocktails. I'm usually pretty skilled with the impact driver but, It took a whole evening after work to assemble them all and I was a little buzzed by the time it was done.
The plastic was dense enough to shim the stripped hole with a kabob stick & Gorilla glue it back together, works fine now.
I went through all of the fasteners and found a few starting to loosen in the bases and glider struts.
