Our frames have been manufactured with quality in mind. They are matte black powder coated steel with 34 support struts in the roof of the frame meaning there is no need for windbars - Contrary to other budget gazebos on the market. No assembly is needed, Erection of this pop up frame is very simple, it has no poles to click into place, just pull the legs out, raise the legs to the desired height, then lock them into place - it really couldn't be any simpler and takes a minute or 2 to fully erect. We advise 2 people to erect the frame however after a little practise it is possible for 1 person. The frame has 3 height settings: Floor to peak of roof: Lowest: 306cm Middle: 314cm Highest: 323cm Floor to edge of frame height: (Head room) Lowest: 186cm Middle: 194cm Highest: 202cm
