I spent a lot of time reading reviews of different versions of balance boards and comparing dimensions, prices, etc. This one appears to be a good value. Intended for a small child, but capable of handling an adult's weight better than some of the competition. And sure enough, baby's daddy (~150#) stood on the board with him to show him how to balance the first time it was in use!
But not to worry. This board is rated to handle more than twice that amount. And it makes a great bridge for trucks and cars, and (sort of) a table.
It's a versatile piece of playroom equipment, tucks away nicely behind a sofa or a loveseat in the living room, or under the bed in a child's room.
TIPS: Use it on a rug to avoid slipperiness issues. Keep the finish nice by not using it on a rough surface, such as concrete.
