What we did at my friends house was get the 4 mattresses from my friends room, his brothers room, and the guest rooms and then put them underneath the balcony in his living room, then get all the pillows, cushions, and blankets in the house and put them on top. we were jumping from the balcony onto the stuff in his living room it was a 15 foot drop and doing some sick ass stuff. then we got a long table from downstairs and ran off that into it doing stuff that was fun too
