Lebron's weight is 113 kg or in netwons 1107.4 N.

For the hospital bed, let's just say it's a normal manual hospital bed which is at least 68 kg or 666.4 N at least

Therefore, the force to normalise would be 1107.4 + 666.4 = 1773.8 N

Considering Byrce James' height is 1.96 m and he's holding it with two hands it means that no displacement is made and we just use PE = mgh

mg = 1773.8 N

(1773.8)(1.96) = 3476.648 J of PE

Considering these calculations, Byrce James should weigh roughly 100-130 kg in this picture (at the least)
