This is a great product and gives my 2 year old a lot of fun. Given that we live in a small flat, it is dead handy to be able to fold up and tuck away. But, to get to that you must be very patient, very strong and don't expect it to be easy assembly - cause it ain't. The frame is simple enough but the bungee cord takes a lot of working and you will get sore hands. You have to thread it round the frame keeping the mat the same distance from the frame all the way round, and keeping the cord pulled tight so as to allow yourself enough slack at the other end to tie a difficult knot to the bungee lock. My wife and i struggled and argued and then i asked her to leave the room and took a deep breath and did it again. TOP TIP - take the bungee cord in your hand before attempting to install it and stretch the hell out of it - every 6 inches give it a real streetttttchh !!!! Then try again and it should go this time. Why-oh-Why can't these people deliver this readimade? i don't know - probably because it's good value for money and at the end of the day you get what you pay for in this world - in this case, swollen red "sausage fingers"
