Hi ks34,
Hopefully you have read post #1 here which is the best place to start your research.
Some of the better options and possibilities in the Tulsa, OK area I’m aware of are listed in post #2 here.
I would also be cautious about memory foam if your new baby will be sleeping on your mattress (see post #2 here which has links to most of the better forum threads and posts about mattresses and children).
