I have the other trekology pillows and have been fairly pleased with them but they didn't have quite enough height for a side sleeper. I was excited to try this. Unfortunately it's a bit of a strange wedge shape from front to back which left my neck feeling unsupported. I tried tweaking it, changing my position etc but it just wasn't comfortable. Maybe it's because I have a long neck. I regret buying it, it was a waste of money for this reason.
