Burt Bacharach famously penned the song “A House is not a Home” way back in 1964 and this can literally sometimes be the case (not that Burt or Hal had sofas in mind). Your home should be a place that you look forward to spending time in. After a hard days graft you should look forward ro relaxing in the comfort of your own home. It should be exactly as you wnat it. The home is a great source of pride for many people. It is important not just that they themselves are comfortable but also their family and friends.
You should take into account how many people are in your household. If you live alone then a nice reclining armchair might do the job where as a big family could maybe do with a sofa set. Consider how often and how many visitors you usually have around. What are your requirements for seating?
