Understand the pros & cons of high back chairs.
If your living room chair has a tall back it can help define your space were as a high back dining chair or bar stool will make a room feel closed in because sight lines are being blocked.
Pick furniture with legs, the longer the better.
That open space under furniture makes your room feel bigger and you can easily push that extra pair of shoes out of the way.
Mirrors are great to make spaces seem bigger.
Vintage mirrors can be found just about everywhere. Home décor stores also have great decorative options. Buy what you love and the bigger the better.
You will always have more space in your bedroom with a small footboard or no footboard attached to your bedframe. The foot of the bed is also a great place to stand and fold laundry.
