Very sturdy for me.  I’m 5’3” and weigh 125.  It’s was perfect!  I like the lifted head as it keeps pillow from falling off.  I had a sore neck from a workout accident when I first used it which was slightly uncomfortable so for the first few nights using it I slept on it backwards.

I used it for almost a full week and found it to be perfect for my travel situation.  Will definitely use it as spare bed for guests as well!
