Review (3/5): DON'T BE HASTY IN ASSEMBLY-PAY ATTENTION
WHEN ASSEMBLING, ALIGN THE CENTER POST CAREFULLY INTO THE BASE OR IT WILL BE CROOKED AND THE SEAT WILL NOT BE LEVEL ALL THE TIME. ONCE THE CENTER POST IS INSERTED INTO THE BASE, YOU CANNOT REMOVE TO RE-ALIGN, AT LEAST I COULDN'T REMOVE IT. HOWEVER, IT ROLLS GREAT, THE SEAT IS A LITTLE FLAT, SHOULD HAVE A LITTLE MORE CUSHION, BUT IT WORKS.
