Chiral solitons coupled with quarks in medium are studied based on the Wigner-Seitz approximation. The chiral quark soliton model is used to obtain the classical soliton solutions. To investigate nucleon and $\Delta$ in matter, the semi-classical quantization is performed by the cranking method. The saturation for nucleon matter and $\Delta$ matter are observed.
