Lost Horizon Air & Foam Camping Mattress for Tesla, Self Inflating Sleeping Pad with Pump Sack, 4.5" Thick, R-Value 13, Model Y

Hi, I found this thread in a Google search - has your experience held up with the Lost Horizons and Hikenture mattresses? Some of the reviews on the LH one say it doesn't hold air properly, and doesn't come with an electric pump anymore. https://a.co/d/05jVMTnY I have a generic mattress pump from Coleman - does any pump work with the mattress, or do you need to buy theirs? I'm intrigued by the Hikenture, but I'm not sure about the pump being totally built in, i.e., what happens if it breaks? I'm a total novice when it comes to camping, so any advice or thoughts would be appreciated! I'm looking to buy some reasonably priced gear to camp in our Tesla for the first time.
