Welcome to the Mattress Forum! … and I;m glad you found us.
You are certainly looking at a good quality/value choice and like the other “simplified choice” mattresses (see posts #1 and #2 in this topic) there is little risk in testing it in your bedroom instead of a showroom since they have a great trial period and return/refund policy.
I’m looking forward to finding out what you end up deciding once you pull the trigger.
