Yup we have one and we love it - so easy to clean.

We use the blow up insert for DD still - but it just gets popped down her back - so we just have that bit blow up and the arms folded behind it.

She doesn't appear to be in any discomfort sitting there and rocks her legs back and forth so I think she actually likes them to be flying free.

She usually is in it for an hour at a time (she loves food and will sit there gumming it to death!!) and she never looks uncomfy.

JMO of course.
