  We investigate the observational viability of a class of $\alpha$-attractors
inflationary models in light of the most recent Cosmic Microwave Background
(CMB) and Large-Scale Structure (LSS) data. By considering a double-well
potential we perform a slow-roll analysis to study the behavior of this class
of models, which is a continuous interpolation between the chaotic inflation
for large values of $\alpha$ and the universal attractor, i.e., $n_s=1- 2/N$
and $r=\alpha 12/N^2$ for small $\alpha$, where $n_s$ is the scalar spectral
index, $r$ is the tensor-to-scalar ratio, and $N$ is the e-fold number. In
order to explore the parameter space of the model, we also perform a MCMC
analysis and find $\alpha=7.56\pm 5.15$ ($1\sigma$).
