Comfortable Bed
Make sure that the bed you will buy is the right size for you. Look for full size bed measurements on the web and plan the lay out of your room well. Leave enough space for other pieces of furniture and, of course, space to move around.

The Bed
The bed is perhaps the most important. Go for a king size bed if the size of your room will allow it. That will give you plenty of space to move around. You will find full size bed measurements in the web so you can make an approximation when you are planning your room.

The Paint
I suggest you go for warm neutral colors when you are painting the walls of your room. This will allow you to be flexible in the color of sheets and other pieces of furniture. I am guessing you don’t want to confine yourself to one design. I am sure you want some sort of flexibility. Neutral colors will allow you to do that.

Quality Sheets
Make it a point to buy only the highest quality cotton sheets you can afford. Remember that this is where you lay your body for a good night rest. There is nothing more rewarding but a real nice sheet when you rest at night. Buy several kinds in solid colors or with prints. You will most likely want to change it often both for hygiene and for aesthetics. Be ready with the different moods you might get into.

Organize
This is often ignored in many rooms. Make sure to keep out of sight everything that is not necessary to be seen. The key to looking neat is to put away everything that does not need to be seen.
