Hi kzookris,
No … you just need to let them know you’re a member here.
Everyone is different and I would be very cautious using someone else’s experience on a mattress or “theory at a distance” as any kind of guideline for your own choices. Either your own personal experience on a mattress (or one that is very similar) or the guidance and suggestions of the retailer or manufacturer on a more detailed phone call will have the best odds of success (see mattress firmness/comfort levels in post #2 here).
