FAQ's
can the radian 3QXT fit 3-across in my car?
Most likely, yes, as long as you have 51” (129.6cm) in the back row from vehicle armrest to armrest. It may be necessary to install all three using the vehicle seat belt system.
can the harness straps be cleaned?
Yes, we recommend using a damp cloth with a solution of water and baking soda to wipe the straps clean. They cannot be saturated in any liquid, or they will need to be replaced. Replacement harness straps can be purchased on our website.
can I use the radian 3QXT from birth?
Yes, the weight limit on the QXT starts at 4lbs. The newborn must also meet a length requirement where the top of their shoulders reaches the lowest harness slot on the seat.
are the harness pads and buckle pads required on my seat?
Yes, they are required while your child is sitting in forward-facing. They are optional but recommended while sitting in rear-facing. The center buckle pad is required at all times.
