You would have to call PJ's because they don't have a website other than that front page. We have the all natural latex, medium firm (IIRC). The boys all have medium plush. I would have bought medium plush for us too had I know how darn comfortable they were ... though ours is very nice too, and probably better that it's a little more firm. There are other on-line sites that I have seen, but for us, PJ's is fairly local and also cheaper. So, I would definitely recommend calling them and asking them if they ship or if they know if their supplier ships. They also sell regular mattresses, so if you do call, let them know that you want the all natural/organic latex mattress.
Another thing to consider is you might want to cross-post in
Finding Your Tribe under Texas and see if anyone in TX has purchased latex mattresses and where they bought them.
