My BIL showed me something when we were camping together at Bodega Bay, a cool little step/stool that is extremely easy to deploy and is very small. I ordered one and was able to put it to the test last week when camping at Blue Lake.
The stool extends from 2.5 inches to 18 inches and can be set at any height in between. It is also rated to handle 397 lbs. The folded up size is a very small 2.5" x 9.8" making it easy to store. Here's some photos;
And here's the true benefit for all who have E Bikes with pannier bags, it fits easily inside and becomes a carry along stool for sitting. This was extremely beneficial when I would have to ride 3 miles to "Signal Hill" where I could retrieve my emails and make phone calls. Sitting for the 45 minutes rather than having to stand made it much more enjoyable.
This stool is one of the better purchases I've made recently. It's small and extremely useful in numerous applications. The price is right and ranges from $19.90 for pink to $26.99 for grey. Here's the Amazon link;
