Finally, a change we can all get behind: "Butt divots" have returned to San Francisco.

The San Francisco Municipal Transportation Agency is bringing back indented seats to comfortably fit riders' rear ends and prevent them from sliding, according to the San Francisco Chronicle.

The transportation agency has recently, and quietly, implemented the new seats, along with other renovations, on one of its two-car trains, the paper reported.

The agency introduced the more modern, "sleeker and quieter" Siemens trains in 2017, which it expected to completely replace its older fleet. However, the new trains featured a significant drawback for riders as the bench seats were flat and slippery, and lacked partitions to divide individual seats.

Muni is now redesigning its Siemens train fleet to include a bucket-shaped curve in each individual seat, formerly known as "butt divots."

An agency spokesperson told the Chronicle that they will redesign the interior of all 68 Sieman trains, a process which would take until 2023 to fully complete.

In addition, another 151 Siemens trains will be introduced as part of phase two of their project, 50 of which will feature the revamped, indented seats.

In the meantime, riders will have to settle for just the one train with the new seats, which the Chronicle reported has been running on different lines and it’s unclear how long it will remain in service for the rest of the year.
