Beware! Purchased Kingkoil Queen size air bed on Jun2025 and start loosing air by Jan 2026. Used it occasionally with 2 grandkids on Fri nights for sleepover. Called Customer Service for warranty replacement 3x and left voice mails as the only choice. Called 4th / 5th time only to be rejected by phone silence. 2nd or 3rd wk after that, Customer service finally returned my call for assistance! However, I had thrown away the air bed and its corresponding /all my documents, thereafter.
