The exact weight that wall-mounted ironing boards can hold varies from board to board, depending on the material the board is made from and how strong the wall support where it's mounted is. Check whether the weight limit is indicated in your user manual. Some wall-mounted boards can hold as much as 25 lbs. of weight, some hold much less. Boards framed inside cabinets can generally hold more weight than bracket mounted ones because they are more sturdily supported. All in all, avoid pressing on the board too hard so you don't damage it.
