Flight 103 yesterday, seat 6A - lumbar deflate about 10 minutes after each reset.
SD Emily was super apologetic while she and I spoke about how ridiculous this is. We got to talking about the personal mattresses - she has heard of them but not encountered them. Emily says she would immediately tell pax to put them away as they are against the rules. She wasn't unsympathetic but rules are rules etc.
As we filled out the form together post flight she commented "at least it was only a TCON." Told her I agree but it was on the heels of a 10.5 hour flight from GRU and it would have been nice to sleep.
Saw/heard her point out 3 seats to maintenance and suggest bladder changes. 3 seats she knew of, but I was the only one getting a form.
