This is really good stuff. I credit it with (among other factors) in reducing my back injury in a crash.

Seat Foam 3 X 16 X 18 Soft/Medium/Firm Density

I tried building a robot vacuum gripper out of CF47 green and had a 4 start experience, but CF45 blue is the right combination of squishy and sealy to make my robot happy. 5/5

I only have 2 inches of available foam to stuff into my seat cushions so I ordered the blue 2 inch medium. This foam is really stiff when cold. However really comfortable when warm. Long summer trips are going to be great.

Seat Foam 2 X 16 X 18 Medium Density Blue

Great improvement in my pilot seat.

Great service

Good product. 1 st one was torn due to a packaging error but as usual Aircraft Spruce ( Carolyn Leon ) took care of it 👍

Just as advertised. Really firm when cold

Looks great and Im sure it will work for my Porsche 914 GT front seat bottom. Cant wait to get it fitted.

Wow! What a difference a pad can make. I fly a j3 Piper Cub and simply cut the pad to fit the existing seat covers. Having the 3 layers really make the difference. Ordered up another pad for the back seat too.

I now have more than seven hundred hours in three years sitting on the three layer laminate cushion. Im sure that a $1,500 dollar seat from oregon aero would be better but they quoted me a six week turnaround! I removed my seat cover and totally ruined mooney cushion, then installed this conforfoam cushion and it is awesome. Remember that it is temperature sensitive so on a cold morning it will be very hard and sit you up higher until it warms up and conforms. frankly this may be the best $100 you spend on your airplane. for any airplane where the seat frame is a pan and not a web this is a must.

Just working with foam now, just big enough for 172n seat bottom with left over pieces for leg bolsters. Cuts fine with a hobby hot wire, but,,,, cuts great with kitchen knives, bread types! Excellent saw-a-bility. Look fwd to firmer support.

The perfect solution for my sore bottom!

Great product, I have used it in three airplanes now. I second the first reviewer, it is firm in cold weather. I also agree and think the soft layer is a bit too soft and causes me to lean a bit to one side. I think the ideal set up would be to use the heavy and medium density only. Thats the plan for the next plane.

Used the tri-layer to replace the seat bottom foam in my C172F in the summer of 2016. Loved it. It did make be sit taller in the saddle by about 2 vs. the 30-year-old previous foam. Then winter came. This foam is as solid as rock below about 30 degrees and takes about a half hour to get soft using body heat. So, at the beginning of a winter flight, I need to extend my seat-belt and my headsets rub the headliner. By the time I land, I need to tighten my belt and I have about 2 of clearance with the headliner. If you will be using this in a cold environment, think about going with 2 of soft and 1 of medium instead of the 1 each of firm, medium, soft. These observations are from a pilot based near Minneapolis, MN.
