After trying and returning different kinds of highchair, I recommend against
any high chair that do not have a built in blocker on the chair. Most high
chairs now has the blocker built into the tray or block from the top, it's
a very bad design because baby must try fit their legs from top into the
chair, like shopping carts.
Only Evenflo high chair has the blocker integrated into the chair so you can
put baby into chair first without the tray, and the blocker is extra safety
measure.
I'm not sure if you understand, but check out the 2 designs to see what I
mean.
