You get what you pay for, so no these are not LZB quality.  But they are pretty darned nice for the price!
Only two positions - reclined and horizontal.  No sitting up with the footrest up.  
The back position is not straight up and down, so a small back pillow may be needed when in the upright position.
Seat is FIRM and is not removable/reversible.  
This chair is for a smaller person.  I am 5ft, in the reclining position, my head comes almost to the top of the chairback.
