Places to Buy Furniture in London and Boston

Hi All,

I'm going to be buying my first home soon with an aim to moving to Cambridge MA in late August, so I've started exploring furniture options.

I'm looking for a leather sofa and leather reading chair and ottoman for the new loft-like apartment. Both must be very comfortable as I'll be doing a lot of reading on them. I'm looking for something with a more contemporary/modern look, but still want a good price-quality ratio.

I'm currently based in London, and so was hoping to start looking at pieces here with a view of placing an order for something I like with a dealer stateside.

Are there any H&M or BY dealers in the UK that anyone knows of? Couldn't find anything on the BY website. Are there any brands with a presence in the UK that people would suggest I look into as good alternates to HM and BY?

Thanks
