This Teepee is sturdy and was easy to assemble. The fabric is a good weight and should last for years. This teepee is actually five sided so is large enough inside for two or three children to fit comfortably.  Our 4 1/2 year old grandson loves it and considers it his private space, although we are invited to get inside with him at times. The 'floor' was not really needed because the teepee is sitting on carpet but I suppose it provides an element of stability. The closeable window is a nice feature to make the teepee a fun hide-out since it can be used to spy on those outside.
