Hi Phoenix
First of all, thank you for your prompt reply. I was (pleasantly) surprised to find your answer the next day, and it certainly helped me move forward with finding a mattress.
I have another question though. I live in the Ottawa area, and I noticed that no retailer in the Ottawa area have your membership. I am looking for a reputable retailer, and I found a page in which you mentioned it here:https://forum.mattressunderground.com/t/looking-for-a-mattress-in-ottawa but that was written in 2011, so are there any changes.
