Hi anon11675,
You can see my comments about the Sleepopolis Blog (and many other similar “review sites” which are really just revenue sites) in post #11 here and in posts #4 and #6 here but the good news is that you ended up buying a great quality/value mattress in spite of the somewhat questionable information there … and congratulations on your new mattress 
I’m looking forward to any additional updates you have the chance to share over time.
Phoenix
