Rated 5 out of 5 by from Pretty sweet Surprisingly useful. I used this as padding for my Flash 18 climbing three 14ers, then I sat on it at the top waiting for the rest of my group. I used it while lounging around camp. And a member of our group, who did not have a sleeping pad, used this seat pad as the ultimate ultralight pad for her hips, which is a lot better than no sleeping pad. After all, this pad is identical to the Z-Lite sleeping pad in construction and thickness. Another reviewer said they used it as a pillow, I wouldn't. It is too small/awkward when packed down. I also don't think this is neccesary for backpacking. I don't bring it on any trips where weight really matters.

Rated 5 out of 5 by from Don't leave home without it! This seat is what I always bring - and I mean always! Not just for camping, where it keeps my bum warm and happy. I use it when I paddle my kayak bare footed trough the Summer, putting it under my heels for support. Kayaking in the winter - hey, I sit on it for warmth. I bring it to picnics, concerts, travels, well anywhere. I have given this seat away as a gift so many times, only to receive the most positive feedback in return. I honestly believe this product will give you a better camping experience! I've used the Z-seat so many times it's become the cheapest of my most valued gear in terms of usage and value. I am a very big Z lover!

Rated 5 out of 5 by from Indispensible multi-purpose item Do yourself a favor - go pick one of these up immediately. It weighs next to nothing, and is good for all sorts of purposes when backpacking. I use mine to sit on, as a back rest, as a clean surface area when preparing food, to stand on when changing pants (so sock or bare foot doesn't get dirty), to rest my bare feet on outside the tent when removing boots (again, preventing them, and the inside of the tent, from getting dirty), as an extra sleeping pad layer under my hips (side sleepers rejoice!), as a wrap around my dirty/wet sandals when affixing to the outside of my pack, and on and on. Love this thing.

Rated 5 out of 5 by from Awesome addition to the gear chest I bought this on somewhat of an impulse for an upcoming 3-night backpacking trip. For me, it was completely awesome, and one of the star performers on that trip! Here is how I used it: -Seat pad around camp -Sitting pad whilst fishing -Cozy for my dehydrated food as it re-constituted -Suspension/padding sheet that fit perfectly into bladder compartment of my Flash 18 pack -Put under my shoulders on night 1 and under my hips on night 2 to supplement my sleeping pad It packs anywhere, is super light, and is really comfortable to sit on. It's great to be able to sit anywhere and not worry about the dirt, mud, rocks, pine sap, etc. This thing will go on every trip everywhere with me from now on.

Rated 5 out of 5 by from Love this pad! I bought two of these, one for myself and one for my boyfriend. We took these on a couple of snowshoe outings with a group and used them to sit on while having lunch. One time we sat directly on the snow with these pads and never felt the cold. We love the idea that they fit easily in the outside bottle pocket of our small day packs. They are small enough so that your arms don't rub on them while using trekking poles and they are so light you hardly notice them. We are both relatively small. For larger people, they may find them too small to sit on.

Rated 5 out of 5 by from great to protect my tailbone I actually bought this so I could comfortably sit anywhere where the ground is hard (wood, dirt, concrete, etc). Lately, I've been testing it out in my home on my wood floors. I like sitting on floors where my legs are more leveled and I feel more grounded. I previously tried sitting on pillows, but no matter how fluffy or thick the pillow was, my tailbone would somehow always find the floor and I would end up in pain within 15 minutes. I finally got this and I can sit for at least a couple hours without my tailbone aching for when I watch movies. A+. I definitely plan on purchasing a couple more later just to keep in my car for future events (i.e. hiking, picnicking on wet fields, etc).

Rated 5 out of 5 by from Great but needs belt attachment I wanted this seat pad to be instantly available wherever and whenever I sat down. So I attached a couple of loops to fit onto my belt, reinforced by duct tape where they pass through the pad. This works so well that Therm-a-rest should make it this as an option. Now after 5 to 10 years of extended usage on the PCT, the pad is worn out, so I'm replacing it.

Rated 5 out of 5 by from Great addition to my system I purchased the silver reflective version of the Z Seat before a seven day autumn bike trip. It served a couple key purposes for my weight-conscious camping gear: • Seat pad for breaks or in camp; on logs, picnic table benches, or the ground. • Insulation under my feet in my hammock. (My upper body was on a Thermarest Prolite Small, and I slept in a 30°F down mummy bag.) The coldest temps at night were around freezing. It worked great for my needs. I plan to bring this system again in the future - it is light weight, packs conveniently, and adds versatility. The other two riders thought it was a great idea and were jealous.

Will this work as a dog camp pad? I am taking my dog on a thru hike and know he will steal my camp pad if he doesn't have his own. Like the weight, but will it fit a 50# collie?

Asked by: lndsyek
The Z-Seat pad could be used by a dog. The foam material may not hold up well to teeth or claws.

I am guessing the pad is designed to have the silver side down and the yellow side up; is that correct?

Asked by: JerryB
The silver side should be up on the Z-Seat Pad so that it can reflect your heat back up at you. If the silver side is down it can be rubbed off on the ground and degrade it's effectiveness in cold conditions.

would this seat stay dry enough for someone duffing(sitting in the middle of the canoe)?

Asked by: Th3ophilus
This seat pad is closed-cell foam and will not absorb water.

Would this be good to sleep on with someone else in a two person tent? 

Asked by: JessicaD
​This pad is only 16 inches wide by 13 inches deep when laid flat, and is best used as a single seat.
