I bought this one, https://www.amazon.com/gp/product/B015KN65UK/ref=oh_aui_search_detailpage?ie=UTF8&psc=1, 15+ months ago and have to say, it kinda sucks.... Can't recommend that one. After just a few uses - we don't jam stuff in it and stretch it out either - it's lost all of it's 'stretchiness'. I guess that isn't necessary for it to work either but it's pretty disappointing. I bought my sister's '08 Infiniti G35 that came with a factory cargo net and after 10 years, it's still like new (maybe she didn't use it ??).

The one I linked to above does "fit" fine though. They come in different sizes so it sounds like you simply bought one that's too large. The one above is 35" wide so look for something in that range.
