If you're talking about step-stools, the W-S ultraslim step stool is extremely light and the easiest one to open-close that I've had. It is pricey, but well worth the $ IMO. We got the 2-step version, and DH cut a couple of inches from the bottom so it would fit in the cabinet (normal height cab--don't know if we'd have been able to make the cab's interior height taller had we planned for this purchase in advance). The step-stool still works well, and I use it often (I'm 5'3"!).

Thanks cat mom! That is exactly what I was looking for!

This Hafele step fits easily in a cabinet or in a toe kick.

I bought one of these for my kitchen and liked it so much that I had to track down another one. I bought the first one at Target but could only find the smaller one there and found the best price at the link below. The man I talked to on the phone to confirm it was what I was looking for was so nice and the step stool arrived at my door soon after.

Tricam does make a 2 step and a 4 step version also. The reason I picked this one was that it folds to about 2" and works well for my 12" utility cabinet. Great price too.

Montanamaven - I have the Hafele toekick stepstool. I want to warn other Gardenwebbers mot to make the same mistake. A complete waste of money. First of all, it only adds about 1' to your height--pretty worthless. Second of all, the costs add up - the step-stool, the bracket, AND I had to pay my cabinetmaker to make the toe kick front, PLUS my contractor's extra labor to cut into my toekick to install it. Third of all, it is very unwieldy to unfold to use, and to fold it back up to put it away. It took me quite a few tries to get the knack of it, and I got tired of doing battle with it each time. Fourth of all, it is VERY pricey for a 1' stepstool ($185 before even the cabinet front and installation). The final insult to my budget was that I had to, in the end, still buy a proper stepstool (from Target, for about $35) that unfolds easily and actually gives me the height I need in a stepstool to reach my upper shelves. I am short, so anything above the second shelf I need a stepstool.

Have I convinced you?

P.S. My inexpensive Target stepstool is quite nice, lightweight, unfolds easily, stores easily, and sturdy. However, I agree with Cat_mom that the best one on the market is the elegant one she linked to at Williams-Sonoma. I'd recommend the 3-step version.

I'm linking to a thread showing clever ways people store their stepstools.
