    Since most builders are always in the market for a good lightweight seat, I thought I would put this out for consumption. They are not the absolute lightest, but they are strong, comfortable, and well made....as well as reasonably priced on Ebay. The picture that has the weight posted is with a seat that has a metal mounting bracket attached, so the seat alone is even lighter. I'll also post a picture of the bracket mount in the floor of a Razer, so you can see how they fit together. They are adjustable. If this works in an off road vehicle, it should be strong enough for an airplane, although I'm sure some pilots will test that theory. They are easy to remove for service access. Think you can get a pair used for about $200. Just check Ebay occassionally. Also, the slots under the headrest give nice points to route seat belts.

    I think it would be considered heavy. That one seat weighs about as much as the rear bench seat of a ,Cessna 172. I’m
    Guessing that one weighs about as much as one rear Cirrus seat which is not a light weight plane. 10-15 lbs is usually the target. It’s going to depend on plane and mission. Loose 6lb and swap it for one gallon of free gas. 60 lb is 10 gallons; a lot of fuel.

    A friend has an old Stits Playboy and the seat is a B-17 gunner seat that looks pretty much like that office chair.

    The linked site says the seat weighs 2 lb 13 oz by itself, and the base adds 13.5 lbs, for a total of 16 lb 5 oz.

    This seat cost a total of $4 of material from an Army Surplus store plus the 4130 tubing. Also can unzip the seat cushion and stuff in a change of clothes. There is a pouch sewed on the rear of the back of the seat for storage.

    There are of course many ways to build a light weight seat if that's the only consideration the builder is looking for. I think most pilots will want to opt for seats that also provide reasonable comfort as well as safety , but in a home built airplane each pilot gets to determine what they believe is most important. The seats I posted are compact which works well with the narrow width available in an airplane. They are already upholstered, padded, bolstered on the sides, and compatible with a 4 point safety harness. They have the bracketry to be both adjustable and easily removable at a reasonable weight and cost. I think it would be difficult for most home builders to build anything with all/most of those features and match/or better the weight and cost of the Polaris seats. While everyone needs to be reasonable about where they allow/or pare excess weight, I think a builder needs to consider all the ramifications of using any seat which might be uncomfortable or unsafe .Even simple hard landings can take a toll on ones anatomy if seats are not well designed.

    Good job,Pops! You have exceptional experience and resources that most builders don't have. In the example I gave, two seats were available for less than $200, so for a single seat like yours, that's a $100 for one seat. Pretty hard for most builders to build a better seat than the Polaris for less. I do have to admit you did a nice job and the Polaris wouldn't be "period correct" for what you are building.

    Right , "Period Correct". That is what I was wanting , plus light and cheap. In building this airplane I was trying to see just how cheaply I could build a fun little airplane that looked and flew like it wasn't an ultralight. Have to look at my notes, but I think I had about $3850 in the airplane at the first test flight. I have to look the amount up tomorrow. Past my bedtime.

    Added --- I'm looking for seats for the VW Pipe mud buggy that I am building. They look good.

    The seats in new airliners are just 1.7 kilos per passenger.

    See the "Farm Use Only" sign on the side of the door. In my area there are lots of bears, 40 lb wildcats and an occasional Mountain lion. Don't leave home barefooted. This airplane has seen a paved runway 2 times.

    The plane looks good. You ought to contact Kitplanes or EAA Sport Aviation and see if they would do an "Affordable Flying" article about
    your airplane.
