Hi carlinskie,
You certainly made a good quality/value choice if you prefer a firmer polyfoam mattress … and congratulations on your new mattress 
I removed the link to your referral code (as I also have with all the others that have posted them … see posts #36 and 37 here) because they are against the rules of the forum but some of the members here can private message you if they wish.
Thanks for letting us know what you ended up deciding and I’m looking forward to your feedback when you receive it.
Phoenix
