It took us one sleepless night to realize that this was not our mattress. We called and were promised a replacement softer insert but it was never sent. It would have been impossible to do a 30 day trial on this mattress as you can't go 30 nights without sleep. Helix did eventually concede that we were not going to keep it and set up a pick up. It was picked up without problems and our money was refunded. We have no problems with the company, just not the mattress for us.
