Garvee 2-Pack Massage & Heated Stadium Seats with Backrest, Dual-Sided Heating, 3 Temperature Levels, Pockets, Foldable Bleacher Chair with Anti-Slip Mat for Cold Outdoor Games, Camping & Events

These are so much more comfortable than I ever expected!! I have a hard time sitting without a back rest, and I was worried these wouldn't provide enough support structurally, or would just keep tipping backwards if I actually reclined into them. Not at all! The back adjusts to several different angles and all but the most reclined one stay exactly where you want them to. It is 100% stable on a flat surface no matter how hard you lean back. The "packed" mode is flat long-wise, not folded in half, so it's pretty long/tall, but has backpack straps and feels like wearing a hiking backpack. As a chair, it also has a buckle that straps it down to the bleacher/seat so that it won't fall off or get easily snatched up by someone while you're getting concessions. That strap can be tucked away behind one of the zippers for a cleaner look.

Now onto the powered features. They are nice. Not a heavenly massage, just vibrations as much as ~5 volts can get you, but it's a good diversion, and the optional heat mode is nice on a very cold day to separate you from the cold metal bleacher and all the other cold people sitting around you.

The battery packs are not included, but I plugged it into a pack that came with one my heated vests and it worked great!! Just a generic USB battery pack; a phone power bank would work too. For longer events, you could bring one of those portable power stations. Or if you're lucky and there's outlets where you're sitting, a USB wall brick will also work.

If you're out at a lot of outdoor events and need to have more comfortable seats, I would recommend these.

Love these! The size is perfect because it gives you lots of room. It’s easy to set up and break down. I love that you can carry it in your back.

Love these seats, if you spend a lot of time in bleachers this saves you butt and back so much!

These are great, I’m excited to use them this Spring for the cold weather baseball!
