Im about to purchase a convertible seat for my 6 1/2 month old son who has outgrown his infant carrier seat. I've zeroed in on a consistent problem regarding access to the strap and latch located on the seat below the crotch which is used to tighten and loosen the harness. It appears that when in the rear facing position, access is blocked by the automobiles back seat. Ive seen the most complaints and solutions for the First Years True Fit, but Im wondering if this is a problem for every seat based on the way the access area is smashed into the back seat of the car when in the rear facing position. I compared the True Fit to the Marathon 70, but both seem to share the problem. Aside from the workaround solutions Ive already read, is this just a design flaw?
