It's looking like it (might) be a nice hot summer, so why not get a hammock with a stand to laze about in in the garden? I've got one at home and last year it was so much nicer than lying on the grass. Cybercheckout have got the UltraFit Camping Green Hammock (26000) and Stand (pictured) reduced from £60 to £22 and the UltraFit Camping Hammock (106) reduced from £64.99 to £20.
Delivery seems to be about £7.95, or free if you can collect from Stevenage. I've linked to the full hammocks page, as there's ones without stands on there for £8 if you don't feel like buying a stand (stands are well worth it IMHO).
