I recently purchased a Helix Sunset Luxe with GlacioTex. I am a side sleeper. Since using the Helix mattress, I have been sweating all night every night to the point where I wake up dehydrated. Sleeping on my side has also been extremely uncomfortable since receiving the Helix mattress. I wake up in a lot of pain, especially in my arms and shoulders. I understand this mattress is for side sleepers, and the GlacioTex is supposed to regulate body temperature. I'm not sure why mine has made my sleep worse.
