This is truly 7 foot wide yet I have it inside my living room as I do not have a yard. It is an amazing way for my 3 year old to safely get out his energy when we can not go outside without disturbing my neighbors that live under me. It is a bit of work to put together but easy enough to understand and do with 2 people. Strong and durable my husband can lay inside at 140 lbs (we had tested it for strength before allowing our child to use it) it's not safe for anyone over 100LBS so only test it by laying on it if over 100lbs. This is for outdoor use so do not use it indoors unless you have high ceilings and or young children.
