We prove that the quasi-Banach spaces $\ell _{p}(c_{0})$ and $\ell _{p}(\ell _{2})$ ($0 p 1$) have a unique unconditional basis up to permutation. Bourgain, Casazza, Lindenstrauss and Tzafriri have previously proved that the same is true for the respective Banach envelopes $\ell _{1}(c_{0})$ and $\ell _{1}(\ell _{2})$. They used duality techniques which are not available in the non-locally convex case.
