I'm asking because I'm not a bumper expert, does is fall within the guidelines?

Also, Taylor, thanks for the thorough response!
That sounds dangerously like you're in the "not okay" regime of bumper construction.

[R28]
Bumpers must be constructed as follows (see Figure 4‑4):
be backed by ¾ in. (nominal) thick by 5 in. tall plywood.
hard Bumper parts (e.g. plywood, fasteners, etc) may not extend more than 1 in. beyond the end of the Frame Perimeter(see Figure 4‑4).


Figure 4-4


use a stacked pair of 2-½ in. “pool noodles” as the bumper cushion material which completely covers the plywood. Cushion material may extend up to 2-½ in. beyond the end of the plywood.
be covered with a rugged, smooth cloth. The cloth must completely enclose all exposed surfaces of the plywood and pool noodle material. The fabric covering the Bumpers must be a solid red or blue in color. Visually, the red or blue must be as close to the corresponding color in the FIRST logo as reasonable (i.e. to a reasonably astute observer, they appear similar). The only markings permitted on the Bumper fabric cover are the team number (see Rule [R35]).
must attach to the Frame Perimeter of the Robot with a rigid fastening system to form a tight, robust connection to the main structure/frame (e.g. not attached with Velcro). The attachment system must be designed to withstand vigorous game play. All removable fasteners (e.g. bolts, locking pins, pip-pins, etc.) will be considered part of the Bumpers.
Each set of Bumpers (including any fasteners and/or structures that attach them to the Robot) must weigh no more than 20 lbs.
