As Delta Air Lines renovates its gate areas at Hartsfield-Jackson International Airport, one feature is gaining unexpected attention: Seats that some passengers say are too hard and uncomfortable.

The new seats are made of a solid black polyurethane material, making them durable and easy to clean.

Some travelers say the collateral damage is their behinds.

“I was sitting there for like half an hour, and I just kept feeling more and more uncomfortable,” said flier Shelli Godfrey, who also quipped in a tweet: “Did you want to make plane seats more inviting?”

Memphis traveler Craig Smither called Delta “a great airline I have flown for years and will continue to fly,” but added, ” I just don’t get those hard plastic seats.”

He wrote in a tweet that “Delta has the most uncomfortable seats at the Atlanta airport,” adding that the airline “should make the senior management use them for desk chairs.”
