Hi Steve,
I’ll add my thanks for your post. It somewhat mirrors the post I was busy writing at the same time here :).
Like you … I place a high premium on the ability to purchase a mattress that has been tested, is a known quantity, and uses high quality materials. I also love the DIY builds and as you say for the majority of people they lead to a great mattress, but for the minority for whatever reason … they can be more difficult than people suspect.
Thanks again for a great post.
Phoenix
