Just as it says in the title - here are some photos of sofas grouped into pairs that look quite similar. Which of the two do you think is the more expensive version? Don't forget to check out the price differences after the photos!
Pair 1: £1412 vs £269 (excl. sofa). On the left, Arco in chartreuse polyester from BoConcept; right, the now discontinued Kramfors sofa from Ikea with a Bamboo Green cover in Tégner Melange textured cotton from Bemz.
These sofas are a selection from interior design go-to guide House to Home's very own 'Pick of the best modern sofas' which I then paired with an Ikea / Bemz version to match. It is true that many of the Ikea models are now discontinued but that's the point - you don't need to get a new sofa. Recovering your existing one is enough to get the look of the best modern sofas around!
And if you still need convincing, check out this delicious Lotus in Designers Guild fabrics from Heal's which will set you back a cracking £4755.
Could you not achieve that very same looking using the sum of these parts (covers come to £529)?
If I were to reiterate my question posed in the title of this post: 'Which is more expensive: can you tell the difference?', I think I might change it to say 'Which is more expensive: would you pay the difference?'.
