Not sure what this "laminated layered wood" is that you're talking about. That's the definition of plywood. I'm guessing you're looking at a premium grade ply, like baltic birch, or ApplePly. Those are great for furniture, but they're not more stable than MDF. I'd use MDF for your sled, and hardwood for the front and back edge, and for the runners.
Remember to make the front and back tall enough that there will be lots of strength even after you've cut through them with the blade at full height. They should be about 5" tall for a 10" saw.
