It’s worth checking out B&Q right now – it has some great retro-inspired design, although (sadly) most of it isn’t available to order online. Like this Petra retro garden furniture.
If Moonbase Alpha in Space 1999 had the need for garden furniture, chances are that it would look something like that this. Rectangular in shape with rounded edges and a mesh detailing on both the table and seating.
It’s made of aluminium, so should be good for leaving out in the worst conditions – although that might not make for the most comfortable of seating. Pop into your local store, they should be in stock, with a table and two benches retailing for around £500.
