How to Inflate an Air Bed with built-in Sponge Pump?

A similar one to this, but bought at Target (Deco brand but same picture):

The package didn’t contain instructions. The way the pump works is a bit awkward and, for a while, I really wasn’t sure it was working. Went online looking for instructions. Closest I came to helpful advice was this Amazon comment. It eventually did work but it took a while and I’m thinking that maybe, just maybe, I didn’t do it properly.

What I did: took off the cap and valve from the pump and pumped using my bare foot making sure I was covering the hole with my foot while pressing the pump and letting air in while lifting my foot. Because the sponge pump sends the air in other parts of the mattress, it’s hard to see that the mattress is in fact being inflated. There are two other valves on the mattress but they seem not to be used while inflating the airbed using the pump.

It might have taken me less time blowing the airbed with my mouth, especially given the time I spent looking for instructions. After all, I’m a longtime sax player and a lifetime non-smoker. My lungs are working properly.

To be honest, I did feel rather silly being unsure as to how this inflator worked. And I’m not completely reassured. Guess I just became accustomed to reading detailed instructions, even when they’re insufficient. Even a single diagram without any word would have been quite useful.

Now, we need to find out how long this will last as a mattress. We plan to use it as our bed until our furniture comes in from Montreal, which might take a few weeks. Hadn’t noticed the comments on the site saying how this airbed may deflate after just a few uses. The box does include a small puncture repair kit. Let’s hope it won’t be needed under normal conditions.
