I now have 5 nights on the Froli Travel. It is definitely a huge improvement over just the mattress, which was noticeable the instant you lie down on it. We definitely do not bottom out, but that being said, my sore hip issue is improved but not completely gone. On my last trip night time temperatures ranged from the 30's to the 60's and I noticed that I still have slightly sore hips, but only when it was colder at night. I am now wondering if bottoming out was not our issue and that really the issue is the mattress being overly firm when it is colder out (all our previous use has been in cool/cold conditions).
