The instructions aren't very easy to read, as there are just pictures, no words. It says 1 adult to assemble, which I managed to do alone (I am a female, thin build, 5ft 3!) but only just. The frame is a nightmare to put together, as you get the last piece in place, one of the other sides pops out! I had to sit on it, using my weight to hold it in place and slowly wiggle the metal until it finally went in. The padded cover was an absolute nightmare to attach. It shows in the picture to sew it through every 5th hole. But on doing this, when I got to the last section, there were too many holes left over, so I had to undo it and try again, making it up by eye. It also says to pull tight after every 4th, but it isn't clear what they mean by this. But on tightening, the holes ended up ripping. So it was just bodged together in the end, which resulted in it being too tight in places and not tight enough in others, meaning the edge that overlaps the frame to hide it, didn't fit properly in one section. So it keeps lifting after bouncing. Which is quite annoying! Other than that. The actual product is good quality though and my girls love it. The in ground concept it great, but digging the hole was very hard work and you have to make sure the ground is very level (which ours wasn't, so I had to shift a lot of soil to even it out). It is ideal for a smaller garden, where you don't want the trampoline dominating the space. It is very secure and has a lot of safety measures to stop it from moving. Pleased overall.
