Hi, would like to know whether the pool base (2 Yellow Color - the part touching the ground) has a similar dimensions to the top frame? (1 Red Color) Is the pool base footprint larger than the top frame? From the various posts in this forum, the top frame dimensions are 30'11" x 14', are these correct? This is important to me as there is a manhole cover nearby at the location where I intend to setup the pool, just want to make sure the pool doesn't sit on the cover.
