Harder than softer. Think athletic mouth-guard but a little harder. I have only had these properly fitted ones fall out two times in over a year, even with a relatively hard surface They are very durable and good for hard grinders, but I hope that he ships them back to you in a timely manner.

I would say it leans towards medium to hard. Don't know if there is a soft version or not. Hope that helps.

Not overly hard.Moderately and comfortably firm is a better description. I love it.

It's not hard. It has a somewhat pliable vinyl liner. We used the cooler all summer at the beach and we are very happy with it. Bill K

Well I wouldn't say hard, but I wouldn't say soft either. So maybe somewhere in between. Hope that helps. Also I would really recommend them.

The surface is not smooth, it is criss cross textured, with about 1/2 millimeter depth grooves. It is very sturdy and durable.

I can't fully remember the specs but there is about 3 layers a 5.6 in the middle bottom I don't know, and top is 7.4 which was what I was going for. It's firm with a light amount of sinking, bout an inch or so.

hi there, I see your question actually pertains to our Hard night guard, not this Extra Durable night guard listing.That said, our hard night guard has a hard outer layer and a soft inner layer. The outer hard layer provides durability against grinding and the inner soft layer provides comfort while wearing.Sarah

Installed a unit in Las Vegas connected to the Water District to replace a traditional salt based water softener. Las Vegas has very hard water. The Aquios system did not work for this application. Pots, pans, silverware, glasses, dishes began to show deposits almost immediately. Some of the family could also "feel" the hardness of the water in the shower. I like the compactness of the unit compared to a traditional water softener, but it did not "soften" our water. We removed the unit and installed a Morton water softener unit.

Soft bottom. This thing is garbage, ours fell apart after our 2nd 8hr drive. I had to throw it away before my return trip. Spend the money and buy a Thule.

It is not hard. You actually sink into it. Does not scratch. Very happy with it

Don't know. That hasn't been my experience. Has your water gotten harder with more minerals or sediment in it?

I cannot tell. Very soft, durable. Easy to clean with woolite in cold water.

Hard like the photo. Can be squeezed into bar shape. Stays together well once wet.

They are definitely solid and hard. I wanted a softer thing and they ended up almost brittle with their hardness.

Great scale system! I would say a 2 at most. Maybe 1.6... I made an error when I purchased it, I was looking for 50A hardness, as in a 10 on the flexibility scale. I kept it anyway, ended up using it as a liner between my small welder and the welding cart. Bent it around the 90 degree corners with ease. Hope this was helpful.
