We need an about us section wrote for our website including a tagline to use

Num. of words: 100ish
Topic: About Us
Tone: Formal/Professional
Extensive research needed: no
Extra notes:

We currently have a small about us for our new website but just need it reworded to sound professional and very understandable about what we actually do.

We sell sofas online, and direct from shopping centre mall promotions/exhibitions, we are the only sofa retailer that does this so we want to make it our USP but cannot word it properly without sounding like we sell sofas to shopping centres.

Our current writing:

Furniture4u is the Number 1 Sofa specialists in shopping centres throughout the UK. With over 50 venues throughout the UK you can find our sofas in your local shopping centre. You do not want to miss our promotions at Furniture4u, keep checking back to see our promotional sofas at unbelievable prices.

We also need a tagline to use on our flyers & banners

Something like: The UK's number 1 sofas specialist in shopping centres

Providing everything is OK, we will require the rest of our site to be reworded at a later date.
