No. The foot end of the NONOMO® Swinging Hammock can be closed by three snap buttons to keep the baby from slipping out. The high side walls prevent your baby from rolling out to the side. That is why no restricting and uncomfortable safety harness is necessary which ensure a good rest. Still the NONOMO® Swinging Hammock is only to be used under attention. Please also consider your babies' development as well as temperament. Older and more agile kids will be able to get out of the NONOMO® Hammock. Therefore we recommend to hang the hammock about 30 cm above the floor to ensure it can get in and out by itself without getting hatmed.
