I bought this car seat a little over one year ago and I am very glad I did. This seat is easy to carry and maneuver into position into the vehicle. It has the LATCH system and tether for secure instillation for younger children and can use the seat belt for added piece of mind and security. The seat belt runs behind the cushioning so it does not bother or affect their comfort in the seat. The five point harness system is easily adjustable. There are three height options to choose from as your child grows and are easy to switch from one to another. There are also two slots for the crotch buckle for more a more customized fit. The cover is completely removable and machine washable. The only complaint I have arises when washing the cover. The interior foam has shifted from multiple washes. I had to cut small slits in the back of the cover so I could get my fingers inside to readjust the foam into the correct places and I have to do this every time I wash it now. We have used this on the airplane and it fits into the seat well but you can not use armrest on either side of the seat. It has various reclining positions for rear facing children. The knob on the side allows for easy tightening and loosening of the harness system in one simple spot. Great when constant little adjustments are needed to accommodate different thicknesses of clothing. Our airplane ride was nine hours and we have taken three cross-country trips with this seat and my daughter always seems very comfortable in it.
