   Typical setup is wheels on springs that will hold the weight of the steps off the floor but not a user. Have a look at the rolling ladder steps at any BOB store.

   BTW: I love the word "retractical".

   Looked at that solution but they are too big.Am looking at a home made solution using a tube with a plastic ball backed up by a spring that retracts when weight applied.A 1 1/2 inch tube inserted in each leg would be unobtrusive if enough of the ball protrudes so the stairs roll.

   Need some dimensions to get an idea of what might be possible. Pictures would help as well. Are you looking for a commercial solution, or are you willing to fabricate something yourself?

   Something like this might be doable, but again without dimensions and pics I'm shooting in the dark here. You could weld an appropriate sized washer to a appropriate sized compression spring, one strong enough to lift the weight of the ladder, but not too strong than an additional 50lbs or so wouldn't be able to compress it. Once the washer is welded on simply bolt the caster on to it then slide it into an appropriately bored hole. It's only a starting point but if you post more info I will see if I can refine it a bit.

   Rolling a ball over the floor, or putting weight on them, is going to do a number on the floor.

   I've used low profile casters only 1-1/2 tall, and built a skirt around them so they aren't at all noticeable.

   GREAT IDEA!!!Contacted McC and four 1 inch diameter plastic ball devices arrive tomorrow.Screwing the stud into a spring loaded stud with a stop sliding in a pvc tube should work

   Casters arrived.Outside diameter larger than expected but for first model can make it work.No worry about ball scratching the floor as it is plastic and retracts when you stand on steps
