Seated in ours now at a HS Football game. Took a second to figure it out without reading directions, cause who does that? I am happy to report the our butts and backsides are neither charcoal nor frost bitten. Heat is very nice.

I am very impressed with the HOPERAN Heated Stadium Seat. It is well-designed, comfortable, and makes watching games or outdoor events so much better. The heating function works great and keeps me warm even on chilly nights.The double seat size is perfect for extra space or sitting together, and the adjustable reclining positions add a lot of comfort. It also has convenient side pockets and cup holders, which are very useful. The material feels durable and high-quality, and it folds up easily for carrying.This stadium seat has exceeded my expectations. It’s a must-have for anyone who spends time outdoors at games, camping, or events in colder weather.⭐️⭐️⭐️⭐️⭐️

Great quality! Super light weight! I didn’t expect the straps to wear like a backpack for easy travel! Good size to fit someone on the bigger side. The reclining options are great and the heating element takes about 5 min to fully heat up but it’s nice to have both back and bottom of the seat! Standard usb cord so definitely bring a battery pack! Even without the heating the seat by itself is still great!If you go to stadiums often this is definitely a must!

These seats are spectacular, really very comfortable, they fit anywhere, my husband loved them and they are very practical to move around, I highly recommend them.

Great stadium chairs. I love that they can be heated and they are way more comfortable than I expected. Easy to carry as a backpack and easy to open/close and easy to store. Can be a little precarious leaning back if you don't attach them but that is not the chair's fault. I really didn't think I'd want to bother with them but now I don't want to sit on benches unless I have one.

We have been using stadium seats for about 7 years now and they have gone to baseball games, wrestling tournaments, basketball games and football games. These are definitely the most well made seats. We have only had them a couple weeks but are super impressed so far. The fabric is thick and durable, zippers are good quality as are the straps. The thickness of the cushions is nice and they don’t smoosh down after sitting on them for a couple hours. I love that there are two different options for keeping the seat from flipping backwards…the straps or the hooks that are hidden inside the zipper section underneath the seat. Love the pocket for the power pack, the drink holder and the extra pocket. We have used them at a couple of cold games and was able to keep them on medium or low and only used about a quarter of the 20k power pack.

I like the back support and ability to adjust it if I want lean back a little more. They heated up quickly and seem to project good warmth. I like the backpack feature so we can hold onto rails or carry other things when at competitions. Recommended!

We used at football game and were warm and comfortable. The side pockets are nice for you phone. It reclines but we had people behind us so we didn’t recline much out of courtesy. Sturdy construction and easy to carry.

I bought the widest armrest option and I’m glad I did, they are much more comfortable when they aren’t digging into your sides. These chairs are very sturdy and just good quality all around. They have lots of random pockets and places for your things. They hook well to the bleacher or you have the option to buckle them underneath if the bleacher doesn’t allow the hooks to latch. The heaters work well and they heat up very quickly. These are a serious game changer when having to sit through outdoor events that are cold. My only negative that I have to say about them is that they are fairly heavy for a bleacher chair. They have backpack type straps that help even the weight out, but if you’re walking very far with them then you may get tired of carrying them. Still…if you are a baseball, softball, football or soccer parent and have to indoor cold weather, do yourself a favor and get you some of these heated chairs.

I ordered these to use while doing seated work at our plant nursery. Now that the weather is in full fall mode, the heated seats are perfect. The cup holder comfortably fits my 16oz water bottle. I purchased a slim power bank (3" x 5") that when connected fits nicely into the side pocket.I bought the 23" wide size - It fits my husband (6' and waist 34) but in hindsight I think the Super Wide size would have been a better choice.I know we'll use these all fall/winter for work. And then next summer they'll be awesome to take camping and out on the boat!

In love with these chairs to enjoy my children's games, comfortable, easy to carry, chairs have pockets to put your bottle and to keep your keys or cell phone, we can not forget that the chairs have an exclusive heater button for when the cold arrives, love it!!!

I ordered a pair of chairs. The one chair works as described. The second chair does not have a USB power connection. Unable to use heated function due to this. The seller reached out after the concern was found and a replacement chair was sent. The replacement has the correct USB connection. The seller was prompt after they were told about the product defect. Thanks!

Bleachers hurt my back and these save the day! The heat is pretty subtle but it is usually just enough where we live for when the end of the season starts to cool down.

Received exactly what I ordered, the 25in heated chairs. They work great and unfold to carry on your back like a backpack and makes for easier storage on a shelf. You need your own power source for the plug in. The access to it is very easy and works great when sitting on bleachers. They also have a strap that you can put around the base of the bleacher chair to hold the chair in place. Easy to use; size is great for me (larger woman). The item is super light, built well and looks great.

Bought these as a gift. They are heavy to carry, so glad I opted for this size. They head up quickly and stay warm without cooling down. They have been well loved and used! They have withstood many of football games and being tossed in the back of the car and have held up really nice!

Honestamente, este asiento se ha convertido en un imprescindible para mí como mamá de béisbol.Paso horas en las gradas viendo los juegos de mi hijo, y este asiento literalmente me salva la vida. Tiene un respaldo súper cómodo (algo que no todos tienen), y la calidad se siente desde el primer uso. No es de esos que se dañan rápido, se nota que está bien hecho.Lo que más me gusta es que es fácil de transportar, no pesa demasiado y lo llevo sin problema a cada juego. Además, los bolsillos son un plus porque puedo guardar cosas básicas sin cargar tanto.Y el detalle del calor. es otro nivel, especialmente en esos días fríos o cuando el juego se alarga más de lo esperado.No es un lujo, es comodidad real si pasas tiempo en gradas. Si eres mamá deportiva como yo, de verdad lo vas a agradecer

I bought this for a soccer tournament that had bleachers and it was going to be 30 degrees F and very windy. I'm so glad I did! This seat keeps me nice and warm. And on days that I don't need the warmth, I like it for the sturdy back rest. I'm a larger person and I fit into the large size fine. My only minor complaint is that no one can sit directly behind me because it does hang over quite a bit. I bought this for my elderly parents and they can carry it like a backpack without any issues.

The chairs are great! They get warm fast and stay really warm for a long time! They don’t come with batteries so that kinda sucks, but if you buy a decent one you can go a couple usages without charging. They are actually pretty light and the backpack type straps come in handy when you’re carrying other stuff to and from a stadium.

Warms up nicely. Way more comfortable than a metal bleacher. Wish it had a pocket to place a power bank inside to store while in use is the only negative and wish the description really emphasized it didn’t come with a power bank Lucky I already had one and it didn’t use much power in the 90 mins I used it.

Forget needing multiple layers to stay warm. On low setting we stayed toasty warm in 37 degree weather. Used at 5 games and it only used 75% of battery pack total for season. (12 total runtime hours)

I will never go to another sporting event without this chair. It’s literally I must have! We bought a power pack separate heats up the seat nicely. We bought the 25 inch. It is big enough with some room left over for a small child to sit.
