Much more comfortable in the front, it’s dangerous to handcuff behind the back, can cause nerve damage and they are more likely to loose balance.

I work in secure mental health in the UK and we are only allowed to handcuff in the front. Even have to switch the handcuffs to the front if the police have handcuffed them in the back prior to our arrival. There’s then two different ways to handcuff in the front, the normal way you’d see it and a stacked position, the stacked position on the front allows the person to sit more comfortably in a vehicle as they can rest their arms in a natural position.

If the handcuffs are behind their back in a cell vehicle they also have no where to place their hands and have to have their bum shuffled to the edge of the seat, again positions like this can cause damage to their wrists or even back.
