A boson field with a phase transition driven by a cosmologically small quartic self-coupling is considered. While its short-wavelength components are stabilized, its very-long-wavelength components start a 'slow-rolling' phase transition as soon as they come within their horizon. The universe becomes filled with a critical density of 'soft-boson' particles with a Compton wavelength of tens of kiloparsecs. Large-scale structure with present size tens of megaparsecs is inescapably formed by the wave-packet dynamics of such soft bosons. Baryons are gravitationally coupled to this structure. The Heisenberg uncertainty principle prevents soft bosons from falling into clusters of galaxies.
