We're extremely pleased with our purchase. We needed two rows of four to replace our existing movie room chairs so we purchased two three-piece sets plus two single Larson chairs. These chairs are built solid and I have compiled some information that I was not able to find from other Q&As posted here. So hopefully this information will help you. Additional box measurements are listed in my review of the three-piece chair set.
1) This chair come in one box. Some have asked about boxes fitting through certain door openings. We had no problem moving any of the boxes boxes through a 30" door opening (space between two jams, i.e. the physical door size was slightly larger).
W x L x H --> 31" x 36" x 25.5" (122.1 lbs). The weight is printed on the side of each box and it took two people to move each box. I suppose if a single person used an appliance dolly (dolly with a strap/clamp), you could move these yourself.
2) Cup holders are not tapered and are 3 5/8" diameter.
3) Each chair is approximately 65" in length when fully reclined (tip of foot rest to top of head rest).
4) The chairs take approximately seven to eight seconds to fully recline. Both recline and return take about the same time and timing is slightly longer when someone is sitting in the chair vs. doing time tests with the chair empty.
5) Each chair is fully supported and although the chairs hook together with a traditional hook and peg design, each chair has feet which increases the strength and durability of each chair. Best of all, when the person sitting next to you moves (shifts weight, reclines, etc.) you won't feel it.
6) I did not notice how these chairs were powered before buying these and thought this additional piece of information may help. Each chair has it's own individual AC to DC transformer and power cord. They are individually packaged and zip-tied to the bottom of each chair. No big deal but you will need to cut the zip-tie to remove the transformer and power cord. If you plan to conceal the transformer somewhere under the chair, make sure you check for clearances when the chair is in motion in both the fully reclined and non-reclined positions. There is a small green LED light on the top of each transformer to indicate the transformer is powered. After being plugged in for one-day, the transformers remained at room temperature.
7) Each chair reclines to almost a horizontal position. In my opinion, fully reclined would be too far back to watch a movie. If you plan to sleep during the movie, you'll be quite comfortable.
