Honestly, i totally forgot i had the 100 night free trial. I didn't even ever consider sending it back. I love this mattress. I used to have backaches after a night of sleep. I took the quick and easy mattress survey thing and it paired me with the dusk. I chose dusk luxe. No more backaches and i am sleeping comfortable through the night. Unboxing was fast and easy. Shipping took a little while but it was worth it. Thanks Helix. Seriously.
