You're lucky, you don't need a floatation to float. You don't need a life jacket at all in which case.
I agree with USMCsting, it's because of buoyancy. The same idea why boats floats. One more thing, swimming pools waters are sometimes designed to floats swimmers to avoid drowning. Another thing is probably your body is so buoyant that it can't overcome the forces, horizontal and vertical forces, in the water for you to be able to sink.
To prove my point and USMCsting, next time you go swimming, grab an extra weight, anything that is heavy, hold it close to your chest and then dive. The extra weights will counterbalance the buoyancy forces. Then you decide if we are right, for your sake. (Because I know 100%, we are).

Wasn't that covered in science class in high school?
There are several reasons why you rise to the surface and float:
1. Your lungs are filled with air. The air helps you to float. If you mixed 5 pounds of air with 100 gallons of water, you'd see bubbles of air come up.
2. if you weigh the water that you displace (the water you take the place of), the water weighs WAY more than you do. The lighter matter (you) gets pushed back out of the "mix."

Because our bodies are made up of water... This causes the floating.

because the air in your lungs buoys you up out of the water. like a air filled ball, your lungs are full of air, so you float. if you breath out so you have hardly any air in your lungs, you will sink like and egg

You have air in your body and that makes you less dense so you float.

Your body has a lot of air in it's lungs and is less dense than water.

because you probably held your breath when you jumped in, inflating your lungs to the max, making them act as water wings.. lowering your overall body density to less than the surrounding water

You fill your lungs up with air before you jump. If ou exhale you will wind yourself sinking a little!
