Your problem is most probably caused by one or more broken springs. I just went through this same situation. You have 4 sets of springs on each lounger.
The short springs help to retract the chair into its upright position. Have a look underneath both recliners and I am sure that you can figure it out. I did! you can purchase the replacement springs at Home Depot. It would be good to measure or take the broken one with you. They are called extension springs. Hope this helps!
