The frame will fit onto all T3 Pushchairs whenever purchased. An adjustable strap holds the car seat firmly in place. Most small newborn car seats will fit into the frame but check that it sits well inside and is not ‘perched’ on the top of it.
Smaller style newborn car seats will fit into this frame so the T3 can now accomodate three newborn babies. The frame does not include the car seat.
