Is anyone able to help me find something similar to this - but much cheaper please?!

[Wenwes]

I love this swivel chair - but not enough to pay £800 plus for it! Has anyone seen anything similar (not necessarily the same colour, but the same design).

Such an amazing design but that price tag! ouch.
I've no idea why so many of the swivel design armchairs cost almost
as much as a sofa.
The design of the above chair has a very similar profile to a sofa part available at Ikea, it's made in sections & in a few colour options.
The single section from ikea is £310, don't add the ikea supplied legs but add a swivel base of your choosing (from another chair or have a look on eBay) and you could achieve a similar look for around half the price.
(Soderhamn one seat section on ikea website)

It looks beautiful but for hardcore swivelling joy you need arms (on the chair ) so you don't fall off mid-swivel.

This one is £399 although sold out in the green velvet

There is this one too but not such a contemporary style as the one you found

Not sure where you found your one but if you get it here for £800 you can get 15% off by signing up for the newsletter

I’m so sorry - totally forgot I’d posted this. Just coming back to say thank you for the replies and suggestions!

Looks like it would tip over if you sat on it wrong.
