I experienced horrible shoulder and collar bone pain the first couple weeks ive used it. I am getting used to the bed still but so far i have had nothing but poor sleep and very bad pain.

This version (twilight) still sleeps hot. I have an eggcarton topper and bamboo sheets which help, but still get sweaty sometimes.

My wife and I thought this would be a good mattress for us as she has indicated that some of my previous choices have been too soft. We ordered one, decided it was too soft and then the company graciously sent us another but it was also too soft especially during summer. The second one seemed the same as the first and possible softer. We spent a lot but are going to have to buy something else that provides firmer support. I am 6’5” and 250 and my wife is 5’6” and 130

Don't love it, but returning 1st fail was a hassle. Fingers crossed it gets better.

I slept at a friend’s house once per month. The bedroom was lovely and the bed was beautiful, but I didn’t sleep well on the oversized twin. My friend replaced that bed with a full size “bed in a box” and suddenly I slept better at her house than at home!! Six months later I moved into an apartment and needed a new bed and asked my friend for the name: HELIX TWILIGHT was the response. I ordered the king mattress and it arrived a week later and was very easy to move and set up! No more midnight hip pain on the HELIX TWILIGHT!! Meanwhile our old full size in the guest room was not comfortable so we purchased a second HELIX TWILIGHT mattress! As a side sleeper I have always liked firm mattresses, but about 15 years ago I started developing hip pain at night. The HELIX TILIGHT provides the perfect combination of firmness and softness at pressure points.
