Hi scb175,
If you have tested the Tempurpedic Cloud Supreme and it’s a good match for you in terms of PPP then the 12" Supreme would likely be suitable for you as well and it’s certainly a great quality/value choice.
Congratulations on your new mattress 
If you order through Amazon and it’s fulfilled by Dreamfoam then there would be a pillow bonus if you let them know you are a member here.
If you order through Amazon and it’s fulfilled by Amazon then there would be no pillow bonus.
If you order through the Dreamfoam site instead of Amazon then there is a 10% discount but there would be no pillow bonus.
There is more about the benefits of ordering through their different purchase channels in post #2 here but with the 10% discount and their 45 day comfort guarantee ordering through the Dreamfoam site would probably be the best choice for most people.
