Hi darketch,
The Tuft & Needle is certainly a good quality/value choice but unless you have any specific questions then the mattress shopping tutorial includes all the basic information, steps, and guidelines and “advice” that can help you make the best possible choice based on all the parts of your “personal value equation” that are most important to you.
The only way to know whether any mattress is a good “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) will be based on your own personal experience but if for some reason it doesn’t turn out to be as good a “match” as you hoped for then there is little risk in trying it because of their great return policy.
I’m looking forward to finding out what you end up deciding once you pull the trigger.
