Hi Traxion,
I did call Snooze city (because they were listed as a Jamison outlet) but nobody answered the phone so I didn’t have a chance to talk with them. I’m glad to hear they are adding some latex mattresses to their lineup because the more choices there are in the area the better.
I think you made a good choice. Overnight mattress is is discussed in quite some length in Post #11 and onwards in this thread and I think highly of them. I had a very long conversation with Vladimir a few days ago and we talked about their mattresses, the industry, different materials, and also a lot about the new directions the company (Dock1) has taken lately which he (and I) think is a good one. I had the feeling that he enjoyed the conversation as much as I did.
They have some great options both before and after the sale as you mentioned and offer good value as well. Their 4.5 lb foam is also a good option I think for most people and would be a good tradeoff between the softer feel and less motion restriction of a 4.5 lb memory foam and the greater durability but firmer feel and motion restriction of a 5.3 lb memory foam. My personal choice there would be the Bamboo Breeze which is exactly the same mattress without the polyfoam on top which I tend to avoid as much as possible … although it will change the feel of the memory foam which some may prefer and can add some breathability to the top of the mattress.
Overall I think you did well and certainly better than most of your local options
