The words "cheap" and "inexpensive" mean approximately the same thing, but they carry different connotations. "Cheap" implies that the inexpensive goods (sofa, in this case) are not well made, whereas "inexpensive" is simply referring to the price in comparison to something else.
Basically, all three end up meaning the same thing, but with variation of wording.
(Also, watch spelling ~~> sofa <~~ in #2.)
1. This isn't as cheap as any other sofa in this shop.
2. This is the most expensive soaf in this shop.
3. There are other sofas that are cheaper.
