I was unhappily searching for a new highchair because I had owned a 2 year old FisherPrice one, but the cover needed to be replaced, so I called and they told me they do not make that chair anymore so I can not get a new cover  all the restraints were different, So I researched highchairs and came across this one, I was very leary buying this since I could not "see" it in person, so I decided to put my faith in all the excellent reviews it got. Well at first I was disapointed because I was missing parts, BUT customer service was a piece of cake and I was able to order the missing parts on line... I cant stress how easy it was! When the pieces arrived I put the chair together in about 15 minutes. It is very light weight BUT safe and sturdy. Even for my chuncky climbers!! It is not much bigger than a traditional chair, so i was happy with that. The conversion, is just a lift of the chair.   I did not give it 5 stars because it is not perfect, to wash the cover you have to unscew it, (PAIN) you have to use 2 hands to get the tray off, so make sure you buckle your kids in and that wont be a problem..... Cleaning can also be a pain, but arent they all??? For the most part it is very easy to clean,.. So needless to say I am very happy with this chair. I am currenly using it with my 15 month old but my 2 1/5 year old loves to climb into it and sit in it as well.... I am oprimisitic that it will still be around for my 11 week old! Great buy!!
