Bests & Worsts Reviews from Amazon

Upon arrival, everything looked okay, but I noticed the left side was not locking securely when in the fully upright position. When I contacted the seller, they wanted video proof of this issue, but would only accept PDF format. (Super confused at how to accomplish that at this point as any link or attachment would not work.) Would not recommend as they have taken no action to remedy the issue. Without adhering to their very specific and challenging method of proving the issue is present, they don't seem interested in helping.
