Hi, I'm alarmed by some of the responses here, especially as the OP is looking for a SAFE napping solution. In hopes that it'll be helpful, I'm copying and pasting this piece about safe sleeping for babies; there are links there for toddlers, too: www.whattoexpect.com/first-year/sleep-solutions/newborn-baby-safe-sleep-practices/
"Your baby should not sleep on anything else — not a couch, armchair, recliner, bean bag chair, glider, infant pillow or inclined sleeper (like the Fisher-Price Rock ‘n Play, which was recalled in 2019 following reports of infant deaths).
"Sleeping anywhere other than a crib, bassinet, playard or portable crib can increase the risk of suffocation and SIDS, even if your baby is sleeping in your arms.
"As for bedside sleepers? Experts don’t have enough evidence to recommend whether you should use them, but it's best to avoid those and any other sleep products claiming to reduce SIDS risk, as they're not always safe, according to updated 2022 sleep guidelines by the American Academy of Paediatrics. If baby dozes off in a car seat, stroller, swing or infant sling, move her to a safe sleeping environment as soon as you can."
