All colored couches
Couches are blocks that you can place down and sit on, just like Chairs.
However, unlike Chairs, when you place couches next to each other they will change appearance and "attach" to the other block, no matter the color. Couches that are any length of blocks, as well as a couch along a corner (inner) can be made.
They will stack up to 8 in a slot, just like Chairs.
To sit on a couch, simply right-click on the block with an empty hand. To get up, press Left Shift.
Their texture is that of wool, which is sampled from the current texture pack, so they will be supported no matter what texture pack you use. Couches are available in every colors.
Crafting recipe[]
Couches needs six blocks of wool of the same color to be crafted. Just place the wool blocks across the middle and bottom rows.
Easter egg[]
There is an advancement named "Rave couch". To unlock this advancement, you have to name a couch "jeb_".
To do this, name a name tag "jeb_" with an anvil and right click a couch of any color with this name tag. The couch will appear in rainbow color, like the sheep named jeb_. The rave couch is it's own item and can be picked up without changing the couch back to normal.
