One advantage of hammocks without spreader bars is the washability in the washing machine. We recommend not more than 30 degrees. Consider that the first time the hammock may bleach out slightly.
After washing the hammock or hammock chair should be completely dry, so that do not warp.
Please check the ropes at both ends of the cloths and adjust them star-like - if necessary.
Also hammock chairs can be put in the washing machine because the wooden bar can be removed easily.
