Top Side Creeper

I do and love it!

I have one, and use it a good amount.  Works well for hard to reach places.

A little pricey, but very solid and sturdy. I wouldn't be without mine. I love it.

I have one also! I use it to get to hard to reach places on my layout................Rogerw.

It's fantastic. I've had mine for about 4 years. (Micro-Mark)

You should do a forum search.  There have been many threads talking about this in the past. 

Our museum has one, which was purchased at my initiative. It's great if you have room to store it and if your layout is set up so there's room to roll the support legs underneath. It is especially appreciated by some of the older and heavier members who do not have the physical mobility to jump up on the layout and move around. The only downside is the space required to store it - the thing is huge, even when folded. 

I have one, very useful

I have been thinking about buying one. I would probably go with the one that they sell at Micro Mark. Its been about a year since I looked.

Go with the Micro-Mark. Really heavy duty.

A good friend has one and they are very useful.  Solves many access problems.

Been using the Micro-Mark one for years. Top notch piece.

I use these (see below) for under the layout, Harbor Freight, but pretty well made. They work well is you duck. I can't get  on my hands and knees any more, this is the only way I can get under the layout. Micro-Mark also has a mechanic's creeper that is adjustable height I think, or head rest height or something like that. Have not tried one of those.

To others with the Topside Creeper, is it adjustable in height? Don't have a need right now, but might be interested in one in the future.

Here's the under layout stools: 

The one I posted above is from Amazon.  The sub $200 one.  It seems plenty strong to support my 140lb (read 230 here ) svelte body.
