The Butter Sofa is a members-only den item that was released on April 1, 2018, and was formerly available for purchase from Jam Mart Furniture.
The Butter Sofa consists of four yellow blocks of butter, all rectangular, stacked into a couch shape. The largest piece of butter is at the bottom and the smallest are both on the sides of the chair as armrests. Another block is at the back of the sofa. The butter appears like it is melting slightly as there are dripping patterns on the couch. This item comes in only one variety.
- This item has an odd price as it ends in a 3 instead of the usual 5 or 0. Because of this, it is presumed to be an April Fool's Day item.
