We have used this slide only twice, but it is wonderful. Simple to set up. We did place a tarp underneath and actually placed a pillow under the tarp under the area where the children land to soften the landing. Enclose the pillow in a garbage bag so water doesn't seep in.We had 4 children at a time ages three to seven. Weight approximately 32 pounds to 60. No issues.Definitely glad we purchased this product.
