Cottage furniture is becoming very trendy and salable furniture. It feels homy and looks romantic at the same time. Most popular cottage furniture color is white, light grey, mint and worn shabby chic. Cottage design looks old and is mainly used in countryside. This days is very trendy to eat healthy food, do sports and breath fresh air so we tend to live in environment which relates to everything I mentioned. I think this helped a lot to raise popularity of such design because we started to think differently in last couple of years.
Cottage furniture design is timeless so it wont go away like other furniture trends. You can spend a little bit more money and buy quality MDF or solid wood furniture because it will last long. It will still look great after 20 years like it was when you bought it.
