Here are some awesome end tables I came across:
Let me start with this gorgeous set from Israeli designer Hilla Shamia. She takes a whole tree trunk, adds some molten aluminum and ends up with these amazing tables.
This set is actually really similar to the pricey one above, but is a steal at $80 for 2 nesting tables. It can be found at Ikea and comes in white or black-brown online, but I think some stores might still have it in the birch color as well.
This table is totally simple and that's what makes it awesome. It is just a block of wood that can be used as a table or a stool.
I couldn't resist including this one from Ikea. It is actually a kitchen cart, but I think it can work great as an end table. It's narrow and can fit in tight spaces and has wheels so you can easily move it around the room. And, I just love the three shelves. I can see a thin throw blanket at the bottom, some books and remotes in the middle and drinks on top. And it's only $50!
