I think it would have a much better accomplishment, otherwise the bed looks and feels like it has waves or hills. Overall is good, but if they added more pieces to one, it would be better. ### ⭐ 1.0 out of 5 stars This product made my back hurt even more than it ... *by L***E on Reviewed in the United States on June 4, 2018* This product made my back hurt even more than it did prior to the purchase.
