Looking for a low profile potty chair for my daughter.....?

This may seem pretty gross to you, but I keep this one in our vehicle. It is small...and easy to clean for my 3 year old's emergencies. It is very short...small enough for your girly. a href="http://www.target.com/Baby-Bjorn-BABYBJ%C3%96RN-Little-Potty/dp/B000CS9TN4/ref=sr_1_2?ie=UTF8&frombrowse=0&searchView=grid5&refinementHistory=subjectbin%2Ctarget_com_age%2Ctarget_com_gender-bin%2Ctarget_com_character-bin%2Cprice%2Ctarget_com_primary_color-bin%2Ctarget_com_size-bin%2Ctarget_com_brand-bin&searchNodeID=1038576&field_launch-date=-1y&searchRank=target104545&keywords=potty%20baby%20bjorn&searchPage=1&field_browse=1038576&searchSize=30&field_keywords=potty%20baby%20bjorn&field_availability=-2" rel="nofollow"http://www.target.com/Baby-Bjorn-BABYBJ%…/a
