Warping is due to uneven drying or moisure absorption. It can happen to any lumber.
You want to get them back in shape ? Clamp them together and leave in direct sun for a couple of days.

I have made quite a few RB with cheap 5 1/2" x 6ft x 5/8" cedar boards. those are the ones used for making fence around the yard. Right here, right now they are sold at $1.56 a piece. With 6 of them you can make a 3ft by 6ft bed that is 11" high. Counting tax, corner lumber and screws it costs about $14 per bed. That is 75 cents per square foot of raised bed.
