    • Nice chair.
This is the easiest chair I've ever put together. 20 minutes tops. It is very comfortable. The seat cushion is a good size and not too small. It extends almost to my knee. I am 5'4". I can see me using the footrest a lot more than I expected. However, if you stretch your legs out, you can not lean back. I have to put my feet on the foot rest and push myself back but it is not difficult. The only other negatives are that the arm rests are not height adjustable nor can you lock them into different positions. And the lumbar only slides up and down. You can't adjust in and out. Even with those minor negatives, this chair is a keeper for me. ... show more

A comfortable office chair that can fold and be tucked away for when we are wanting to watch tv. We have a room that needs to be used in several ways: sometimes it’s an office, sometimes a tv room, and sometimes it’s used as a guest room. We have Samsung’s The Frame mounted over the desk and it functions as art on the wall, but when the room is needed for tv viewing, the office chair folds easily and we tuck it under the desk. When it’s folded, you don’t even notice that it’s there. This chair is comfortable as well. It The could be used as extra seating for tv viewing if need be. It has a pull out footrest to rest your feet on if you are so inclined to recline a bit while watching tv. We thought it out, read all the reviews and got exactly what we wanted/needed! Happy customers! ... show more

My chair just arrived today in perfect condition. The FlexiSpot Sentinel Pro. The chair went together with no problem. It is very comfortable. 2 things that would make this chair better: 1 a friction adjustment to regulate the recline of the chair. It is spring loaded to return the chair to upright, but it reclines to fast. 2 The bracket that the arms fasten to is plastic. It should of been made of aluminum. It is rather flimsy, I have to say. When you put pressure on the arms to get up out of the chair they move in any direction. For people that play guitar, this chair works well for that. ... show more

    • Great chair for the price
I was looking for a cheap but still good quality second chair for my room. I needed it to be foldable so I can tuck it underneath the desk when it's not in used. The biggest selling point is the arm rest that can be moved up as well. Most chair I've seen only have one or the other of my two requirements. The arm rest going up is super helpful if you play any guitar. I will say I've sat on more comfortable chair but for the price it's amazing. The chair still has enough cushion and it's very easy to adjust. Definitely recommend ... show more

    • Disappointed with the quality
Color: Black Size: arm width 28"
I’m giving this chair one star because it looked great at first, but in less than two months one of the wheels completely came off while I was using it. For the price, I expected much better quality and durability. Now the chair feels unstable and uncomfortable to use. I would not recommend it for daily use. ... show more

    • Pick your battles
The seat is comfortable and the material is feels nice. Tilts back nicely. I think that the back is a bit loose. When sitting up straight, leaning forward or getting up while using the armrest for support, the back leans forward. Lumber support tends to drop down after I get up, having to adjust it each time I sit down ... show more
