Well the seats finally arrived yesterday. So it was a little closer to 8 weeks then the original 4-6, but I expected this since it was coming from Palliser. Apparently their pretty backed up, and another vendor told me it could be closer to 3 months. So I'm still happy with the delivery time.
As for the experience with theaterseatstore.com, I'm happy to report that everything went smoothly. I had called a couple of times to check on the progress, and they were able to give me an update from Palliser. The staff was friendly and helpfull. The minor blemish in the process was when the seats were shipped from the manufacturer to the shipping company. Apparently the shipping company was given notification of the shipment, but not the proof of delivery. When I called theaterseatstore, they followed up with the shiping company and later that day I got a follow up email from theaterseatstore, and later the email to schedule delivery from the shipping company.
The shiping company ended up being Last Mile Home. The delivery truck arrived in the first 45 minutes of the given 4 hour window. The delivery people were very friendly and courteous, allowing me to fully inspect each chair as they set it up.
As for the chairs themselves, I am very happy with the result. They arrived in perfect condition. The fabric is somewhat leather like, almost something between leather and the typical microfiber. I find it to be very soft, and not have the breathablility issues that leather has. When we sat down to watch a movie last night, they were slightly cool, but not as much as my leather sectional upstairs. Through the whole movie, they remained very comfortable, and didn't generate any hot spots that you can get when sitting on leather for a while. So this ended up being exactly what I was looking for.
As for sound, they helped tame some of the echo that I have in my room. I still need to get some acoustic panels up to really get the job done, but this did make a noticeable difference.
I'll give another update after using them for another week or so. I'll also try to get some more pictures up.
