    On the other hand: Cold day and automatic choke = higher revs. Perhaps slight slope on road. Could lurch just enough to run over your foot and sit there with the handbrake still on and of course you've already said there was no one around. ;-)

    Kitchen Helper Tower

    Hi ghochmanWhile the legs are slightly wider than the top section (33mm), this does not remove my concerns. As my main concern is the child grabbing the worktop and pulling sideways, can you do a test for me please? If you have a luggage or fishing scale can you hook it to the top left or right rail and measure the force required to start a tip (without the child on top). I'd be very curious to see the results.

    I genuinely have a safety concern with this design due to it's top heavy nature.I have that stool and it's very light at under 3kg. I'm sure the structural studs and fittings weigh more than that. Then we add the weight of a child (lets say 12kg for the sake of argument). Now we have a scenario where the top fitting is approximately 5 times the weight of the base. If stretching for something off to the side (like that knife your trying to keep out of reach) the child's weight will act on the side rail. I.E. Very high for a high center of gravity design. As the child is confined they may well try to pull on the worktop to get closer to that thing they want to grab. Once this tower tips the child will have no way of saving the fall - unlike a fall from an unenclosed stool where the child'...

Once this tower tips the child will have no way of saving the fall - unlike a fall from an unenclosed stool where the child's reflex action to hang on will at least make their head less likely to hit the ground first.I did a test on the basic stall and it takes just 1kg of force at the platform of the stool to start it tipping sideways. I'd guess it would require less on the upper rail in your design. I suspect also the amount of travel required for a topple is within the reach of a child.I think anyone building this needs at least to add some stabilization to the sides and probably to the rear too.

    I really like the simple but elegant design you've come up with. Sturdy, cute, fun!
