My husband and I are both side/back sleepers, and overall think this is a great mattress (been using it about 2 months). We went from a 12 year old spring mattress that gave us hip and back pain to the Helix Dusk Luxe and are overall pleased. Took about 3-4 weeks for "break in" time. The only issue we have with this is it is a little softer than expected. We are still within our 100 days of purchase, but we don't think its softness is enough to make us want to exchange for a firmer mattress. Price is reasonable as long as it lasts as long as it claims. No issues sleeping hot. I would purchase a Helix again, but might would consider a firmer mattress.
