Thank you for such a thoughtful reply, Maverick!
Interesting idea about the log rolls for reducing ear support! I have experimented with a “cervical roll” at the base of my pillow, and is actually how I’ve used the wool bolus. However, with the space it took up in the BioSleep cover and the reduced fill in the layers to accomodate for it, made the pillow to flat.
Prior to that, I tried a wool bolus/lanoodle two-chamber layered arrangement, but I found it too firm and flat. So I switched to kapok for that softness and easier loft.
I have experienced a lot of the things you mention about the Bio Sleep: thicker and more structured, resulting in more surface tension. I am interested in trying out the Bedroom & More wool cover. Is there a link you can share to the European Sleep Works “stretch cotoon envelope style” cover? I’m not sure I fully understand how it works from your description, and Google didn’t turn anything up for me.
I am going to try a different cover and experiment with the horizontal rolls.
