Therm-a-Rest Lite Seat Ultralight Inflatable Seat Cushion

Me parece muy cómodo. También es ligero, ocupa poco y aísla bastante bien del frío

Pros: Compact, light weight and easy to use.Cons: A little expensive, no instructions(even though packaging states follow included instructions).Overall I'm happy with the cushion. The foam maintains and improves comfort. I have been using my cushion for less then a day but I like it. I haven't noticed any leaks yet.

I'm going to be traveling again soon, and one thing that I notice when I fly that the seats in economy really kill my lower back over a long flight. A little old lady who sat next to me last time brought a seat cushion with her, and it was like a lightbulb went off in my head. So before this trip I set out to find a decent, but easy to carry seat cushion.I landed on this one because it's inflatable, and packs up in a nice small space that won't kill too much of my carry-on capacity. A lot of the options out there, particularly the memory foam options, are way too large. I don't want a seat cushion filling up half my luggage.This... works, more or less. It inflates easily, and when I put it on my office chair (which also isn't the best for my back, I really should talk to them about buying me a new one) it definitely served to pad things better.The problem? It's too small, and I feel like I barely fit on it. If I end up with it in the wrong position, it actually makes things worse. It saves my back by making my legs and my knees hurt. Moving it around, I've managed to improve the situation, but I always have to fuss with it every time I sit down to get it (and myself) in just the right spot. If it were just a few inches larger in both directions, I feel like it would fit the seat better and probably fit me better.Still, for lack of a better option, I'm going to keep it and try it on my flight. It will, at the very least, almost certainly be better than nothing. I am going to look for a better cushion for my office chair though (no need to worry about packing space with that).By the way, one thing that I've found does help, don't over-inflate it. Since it's self-inflating, that means you generally have to push a little air back out after it has inflated. It's a lot more comfortable (in my opinion) with a little less air in it than it is fully inflated.

Instant upgrade the foam in your seat to business class. Used on a few 15-hr flights.

座り心地がいいのはもちろん、寒い冬のコンクリートの上でも冷気を感じないので快適です。
