DESCRIPTION
INTEGRAL-A402 is a dual channel, 1U, high efficiency class D amplifier intended for permanent installation use. It is equipped with switching universal mains power supply and auto-standby functionality when no signal presence is detected providing energy savings.

Misinformation!
Color: Dark Black, Color: Dark Black
Be aware that this does NOT ship with a class 4 gas lift. The whole reason I bought this chair was because it shows in the advertising this comes with a class 4 lift. Have contacted the seller and gotten the "we have a 1 year warranty" line. I am in the 300+ lb weight class. I have had many MANY other class 3 lifts and I know it will work as intended for about 2.5 years, and then it will slowly fail and not be able to stay up.

Nice and Sturdy. Great quality
Color: Dark Black
This a very well built sturdy chair. It was easy to put together and it came very fast in the mail. I have had 2 other office chairs made by other compaines and they were nice but they both seemed a little loose and not solid enough. they all lasted less than an year. This one is solid, well built and will likely last a lone time. It is easy to adjust also. Its nice and wide also.

Great find!!
Color: White Rose Velvet, Color: White Rose Velvet
This thing rocks. I hope it lasts longer than my last gaming chair bc it was double the price. It arrived days earlier than estimated, is soft, comfortable, and really pretty. I did not love the instructions, but I figured out assembly without too much trouble. It reclines without falling over and goes up and down smoothly. My cats immediately love it, so I’m really happy! Let’s hope it withstands longevity.
