I watch a Nissan Altima commercial today and they advertise 0 % gravity seats inspired by NASA.

How do they work, or is this just hot air to sell a Nissan??

Cheers!

It's pure bull****, they're claiming they used NASA research to make the seats more comfortable.

Yup. You become weightless in the new Altima.

People do complain of becoming more car sick though.

I feel good in my RX seats. No need for weightless

I find the Altima's seats fairly comfortable for the category and price range of the vehicle.

The key word is "inspired" by NASA. so forget about the zero gravity...

As far as I'm concerned, these commercials are like the ones the same company (Nissan) used several years ago showing dogs driving their products. About the same level of mentality.

It's marketing, but the seats themselves are actually very comfortable. They're only in the front seats though.

Designing seats to simulate an occupant in a weightless environment is intended to minimize the muscular loading of the occupant’s back, pelvis, and torso. This is accomplished by developing the seat’s shape and support system to put the occupant’s spine in its natural position.

The seatback shape and its patented structure provides varying levels of support in the lumbar, midback, and shoulder regions to position the occupant’s spine in its natural position. According to NASA seating and posture research, a seat design that correlates to low occupant fatigue is a design that mimics a body-neutral posture—essentially the relaxed position the human body assumes in a weightless environment.

It's based off of a massage chair zero gravity seating position concept:

http://electronics.howstuffworks.com...age-chair1.htm

"Zero-gravity massage chairs can assume the same position to help distribute a user's weight across the chair. The manufacturers claim that this relieves stress on the body and allows for a deeper, more intense massage experience. Some manufacturers claim that the reduction of stress on your body is so effective you'll feel virtually weightless as a result."

I'm sure part of it is Marketing BS, but I can see where NASA research could be utilized in seat design. FWIW when the redesigned Altima came out last summer, I test drove one, a midrange model (SV I think), and the front seats were great.
