This is a nice product. SET UP: This product is easy to set up, and should take maybe 10 minutes. It DOES NOT come with any instructions. It should, especially for someone who has never set up a tent before. If you haven't ever done so, it would be best to refer to the photo on the box. Basically, set up consists of laying the tent flat on the floor, assembling the two shock cord poles (screw each of them together by tightening the pole pieces into the attached couplers, and then thread each of the two poles through one set of loops. The loops run from each of the four bottom corners of the tent, up to the roof, and back down to the opposite corner. There are ties at the roof top to fasten the top of the tent to the poles as well. We bought the tent for our 8 year old and she loves it. DESIGN: The tent is colorful. It is the size that is advertise, slightly under 5' by 5', and around 4' high in the center. One of the four walls has no openings. Make this your back wall if you want to place the tent against a wall. One wall has a full zippered opening (best access point for large adults). The other two walls each have a round opening and a "door" which can be draped and fastened over the opening, or rolled up and fastened for entrance. An adult who is not real big can use these holes too (small frame). Inside the tent is roomy. I am a average height for a man and about 210 lbs, and I sat in the tent with my 8 year old and there's still room for a couple more kids, teenagers, etc. Usually, its my 8 year old, her 13 and 21 year old sisters and 16 year old brother. So it will easily hold a few kids. The tent has a plastic floor, which seems durable. it is not too flimsy, but it is also not an extremely heavy gauge. Again, it's a play tent. The roof is mostly mesh, which allows for some privacy for the kids playing in the tent, but still lets parents supervise them. It also provides air flow and lets hot air rise up and out. USE: This tent is very roomy, just allow space in your home for it. 5x5 is a fair amount of space. But it's nice because it allows for adults or older siblings to fit in the tent and play with their kids/younger siblings. It is advertised as an indoor/outdoor tent . You absolutely can use it indoors. As for outdoors, I would note two things: Typically you tether an outdoor tent, even a small one, with cords and stakes. There are loops, etc. on this tent to do that, but you would need to supply your own cords and stakes. The other thing is, as mentioned above, the upper portion of the roof is a "mesh" weave. If it was raining to any degree, the water would enter. Overall, this tent is a great price, the set up is quick, and it seems sturdy enough. I think it is high enough quality to hold up to some rough housing, but of course if kids jump on it, then can break parts or knock it over. It is a nice size. My kids love it. They sit in it at night and play cards and "camp out" with a lantern and some snacks. I really don't think you can go wrong with this tent, especially since it costs no more than a couple of DVD movies. I would have given it 5 stars, but gave it 4, as selling any product that requires assembly without instructions is nonsense. While it is easy, especially if you've assembled tents, the maker should include directions for the novice.
