Do they have grip? Like a sandpaper feel? To those who stack, you just place one on top and they stay-no sliding? BTW-the angle is 18 degrees for one.

Yes they have some grip. I do stack them together for a steeper angle and they work fine with no slipping.

No grip-you cannot stand on these without gym shoes. They have a pebble like finish. I like them and use them on my off days from therapy - but never without gyms shoes. The angle is 18 degrees for one slant.

They do have grip, but not like sandpaper. They are very sturdy, firm, dense, but porous -- similar to pool noodles but FIRM. I use one under my pillow and hang my head off the edge for a neck stretch. It doesn't slip. I even have some trouble moving it because it doesn't slide easily on the sheet. However, it does leave little black specks of the material coming off. I have never stacked the two, but I don't think they would lock or grip together and be safe for standing. I hope this helps.

Yes they do have some grip, not a non-slip sandpaper level of grip, but I don't find that my feet slip off.

Yes, they're rough like sandpaper. I tried putting one on top of the other (that's quite a stretch!) and there was no slippage.

I returned these for one that was better made. They do stack, I can't remember whether they have sand paper or not, but I would recommend the Thera-Band Rocker Board as I am VERY HAPPY with it. I REALLY LIKE it.

They lay flat, as far as sticky... well, the ones I bought aren't very sticky at all. I had a plastic bag land on one and was able to pull it off without ripping it. Save your money and look for another seller.

The tops are flat and I have them stacked (2). There is a very slight "lip" on the top that helps to keep them from sliding off.

They are kind of a pain! I try to do it like my windshield shades. Grab them at 3:00 and 9:00, twist your hands in opposite directions (from each other) and move the sides in together at the same time. It takes me several tries, but eventually works.

If I understand the question correctly, poorly. They do not seem to be designed to interlock for stacking in any direction.

If they are not frozen first they will stick together upon freezing. I do not stack mine.

They don't interlock in any way so they are not completely stable...but they are also not curved so they can stack. I would say it depends on where you put them and how much activity is around them. I stack the two smaller ones together and they do fine. They are not in a high traffic area and I only use them for baking (so like once a month or so).

No...very simple. Follow instructions provided. Took me a few minutes. You'll also be happy with them...they really stabilize your grip.

No, they have a non-slip coating on both top & bottom. I've experienced the design to be very stable.

Sorry do not check this e-mail often:) but no they are not stable if stacked on top of each other. Can you do it? sure, but would not recommend it.

I used them upside down before and they didn't scrape. I use the inserts mostly for hills.

They tip over Very easily. We don't have any children, so it's not an issue with us. Hope this helps.

We have them stacked 3 high and they do not tip. I would say depends on what you are using them for... We have nuts and bolts in ours but they have many uses. They would not tip easily though, they are well constructed and sit flat on a surface.

I haven't noticed them being slippery, the probably do some but I have been very happy with them for the price.

Yes, they are "crazy" strong!! The best way to do it, is to hold them next to a sharp edged counter. Then push the top one off onto the counter and push it away. Only do One at a time, and only have a couple on the counter at a time... So don't sling back together. I found this by googling the question... I think there was actually a video on YouTube.

They mostly stay stacked. The top two (1/8cup and 1/4 cup) tend to slide around a little bit because they are the smallest and lightest and may not line up directly with the handles below. I keep them all stacked in my cabinet and it hasn't been a problem. They are not entirely flat though, no.

They do stack, though don't go higher than 4. Each one has little bumps for feet. You'll live them;)
