For all of you folks who have bought some garden Furniture that didn't come with it's own parasol I have found this one from Argos, got it home and have to say I'm quite impressed it is a lot bigger than expected maybe the 2m one would have done me but it was more expensive than this one.
Parasol size 270cm.
Height 246cm, with pulley system.
Packed flat for home assembly.
Self assembly: 2 people recommended.
You can also get a further 20% off if you buy it in conjunction with a base.
