How much does treated plywood weigh?

It depends what the "ply" value is ... the number of layers glued together. For instance, 1/2" plywood is going to be lighter then 3/4" plywood. A common rule of thumb is a 4x8 foot sheet of 1/4" fir plywood weighs 25 pounds. There are 32 square feet in a sheet, so a square foot of 1/4" fir plywood weighs about 0.78 pounds. Since 1/2" is twice as thick as 1/4", 1/2" fir plywood weighs twice as much, or 1.56 lbs, and 3/4" three times as much, or about 2.34 lbs. Fir plywood is common, but other species are available. Weight varies considerably between species of wood, so be aware the weight of plywood of different species can be different.

Where can you get plywood for full mattress size?

A full sized mattress is 54" x 75". If you want an edge around the mattress (for example, if you are making a platform style bed) then figure out the edge you want and calculate accordingly. I always use a piece cut exactly to the mattress measurements, and that works fine for me.
