Description
We present a stable cosmological model of a closed universe in the presence of conventional scalar
field. The stability of the model and the absence of singularity is ensured by spatial curvature
without the need for additional peculiar matter. We reconstruct the Lagrangian and numerically
compute observational predictions, including the number of e-folds, the spectral index $n_s$, and the
tensor-to-scalar ratio. We present several sets of parameters that satisfy the current observational
data.
