a month later, I am not at all satisfied with this product for use ....
First it's too heavy ... my computer is already a big laptop suddenly the two together to handle this is not practical especially as the table legs fold (they are not provided with a system that would block a certain position, which is a shame when used on a support as the mattress is soft) ... So yesterday I strongly pinched myself a finger.
the foot position "up" does not hold and is not practical to implement.
So I prefer to do without it ... unnecessary purchase !!!!!
