The Voice UK coaches have admitted that their trademark red chairs are the most uncomfortable things ever.
The giant spinning chairs at the Voice's gimmick, but the superstar coaches confessed sitting in them for any length of time is painful.
“They’re round on the back so they make you [hunch]," said Will. “I don’t know why they have them like this. They’re not like that [on The Voice Australia].
“I sat in Seal’s chair. Their chairs are different, they’re straight. Ours are curved in so they make you do this all the time (hunches over again).”
The chairs, which weight just under 19 stone each, are also too big for both Will.i.am and Sir Tom Jones' feet to touch the ground!
“I feel so little in that chair — but at least my feet touch the ground. Will’s don’t!" Jessie J laughed.
But Jessie did agree with Will on the comfort factor, telling the Radio Times last month: “Honestly, as a girl, it’s not the most comfortable chair.
“While all the guys can sit back and look relaxed, I have to sit really upright and forward or lean to the side.
The Voice UK continues next Saturday night on BBC One.
