There are numerous Ribe space constructions but ultimately they produce the same general object, a quasi-Banach topology on the direct sum of the real line R with the Banach space l_1 of absolutely summable sequences. In all constructions R and l_1 are algebraic complements but R is closed and not complemented topologically. Every such space is non-locally-convex and Rademacher type 1. However, some embed into Lp for 0
