However, you should take your time to figure out the overall size of your room. Will it take up too much space? From there you will know the dimensions and shapes that will work best for your home.
Think of your priorities
Is your focus mainly on beautifying your room or are you more interested in functionality? Think about this so that you will know for sure what to go for.
If you're thinking of something that is meant to just make your room look more interesting, you will be free to pick different materials and designs. But, if you want something that is fully functional, you can choose more sturdy materials and designs that are comfortable to sit in.
Stick to a specific color theme
Although accent chairs should be bold, you still want something that can harmoniously match with the color scheme of your room. Always remember that random colors never bring proper visual balance.
One way is to pick a shade of color that is similar to the rest of your furniture. If you have navy blue couches for example, you can go for sky blue accent chairs.
Another way is to choose colors that complement each other. To gain more knowledge on color coordination, a quick check online will demystify the color wheel giving you a clearer picture of the options you have.
Choose a pattern that matches
Besides the color, you should also be careful when choosing a pattern. If you choose a pattern that's busy or one that doesn't flow with the theme of your home, it will definitely look off.
If you're not sure, keep it simple. You can also consult one or two friends who have an eye for interior decor to get their perspective and suggestions before making a decision.
