We have a smaller non slip version of this and our kids and family have been enjoying it for a while. We bought it from Revain stock with "cosmetic blemishes" that were fine with us. A giant well-made blower, this inflatable house is definitely suitable for children under 8 years old. It may be a bit unstable if not secured due to the height. but. However, the main negative stars go to Revain Warehouse and its customer support team. Blemishes were actually holes that needed patching. Looks like they never tested that. No substitute options, no suggested solutions. just told us to figure out how to pack this thing up and ship it back. All this to say that we like the jump house, but we will buy it elsewhere.
