Removalists are really good when it comes to furniture. I remember when my flatmates and I moved into our first flat on the top floor, we struggled to haul a big heavy sofa into the flat, but when we moved out we hired some removalists -- two little unassuming looking dudes -- and they just picked it up, carried it down several flights of stairs, loaded it into their truck, then came back up to load more furniture without so much as breaking a drop of sweat!
