Trying to append a mesh from 2.8 to 2.7, but it appears to be corrupted?

So basically, I really need to import a mesh from 2.8 to 2.7, however when I do this, it just seems… off.
Its a chair, and the faces on the back of it seem to be invisible (kind of… I cant even really explain what’s going on here.) I also can’t select any faces on it, period.
Is there any other way to import a mesh? Am I appending wrong?

mesh should mostly append in 2.79

but it is not backward compatible
many nodes for mat have been modified and won’t work in 2.79
also particles and cloth have been upgraded too!

so better stay in 2.83 !

happy bl
