Noble House Elmore Fabric Upholstered Wood Dining Chairs, Set of 2, Light Gray and Weathered Gray

i ordered two sets of these chairs. the first set was perfect! easy to assemble and great quality for the price. the second set came with uneven legs, and when I noticed this, I realized there is not a way to lengthen the legs. the glides on the bottom of the chair legs are fixed - you cannot twist them to even out the legs!!! so now I have a wobbly chair... and I don't want to go through the hassle of loading the chairs into my car and returning them (also note I of course threw away the box and packaging!). so this fault will forever drive me crazy.
