Hi all, I'm in week 3 of fundamentals and loving it. I thought this would be a good question to pose here given GB's understanding of the body.
I spent about a month in Asia doing a ton of travel (including a week of intense motorcycle riding in the mountains of Vietnam). I noticed shortly after arriving the beds were very firm and largely forced me to sleep on my back (I generally fall asleep on my back or side and wake up on my side). It took some getting used to, but after that my back felt better.
After my first night back in the US on my american style mattress (memory foam from costco, not super soft but not super firm either), my back started hurting. This hasn't gone away. GB fundamentals are helping a lot, but it seems clear I also need a change in sleeping.
Curious as to any thoughts from the GB team on recommended type of mattress (spring, foam, latex, combo) and any specific models? Same type of question on pillow (low profile, down/synthetic down/polyester, etc).
Thanks!
