I can’t imagine me allowing anyone else to choose or place my furniture but if it gives you much needed ideas then why not. You say it is free and presumably you are under no obligation to purchase anything recommended so it being worth it is not an issue.
I suddenly got completely fed up with our living room last night. It’s never really been thought out properly - the furniture from our previous house was just arranged by the removal men (seven years ago!) and has stayed like that. I did change lighting and curtains but that was it. The furniture is too big (apart from the sofa which is now well past it’s best due to being somewhat overused during lockdown!) On an impulse, I’ve booked a John Lewis free home design service (on-line so that should be interesting). Has anyone else done this and was it worth it?
