Clek Fllo

Does anyone own a Clek Fllo or Foonf? We have a Nuna Rava for our oldest, but I’ve been eyeing the Clek car seats for our youngest. They are well reviewed, but I just worry about the head and body support. When my son first moved into the Rava (6 months) I felt like his head went all over the place, but the car seat seemed to do a nice job cradling his body. The Clek car seats seem so stiff to me and not great at cradling a weak infant, so they seem like they’d be better for older kids. Is that right? Or did your young infant seem comfortable enough in the Clek?

Also, is the back very long? We have a Toyota Highlander and when my son’s car seat was rear facing it took up so much room that I felt my legs were squished in the front seat. Does the Clek seem to take up more space when rear facing?
