Beautyrest Hi Loft Air Mattress: The Beautyrest Hi Loft double air mattress is equipped with an included electric pump that screws onto the mattress. Once attached, it inflates the mattress in about 2 minutes, although not as fully as I would like. Once inflated, you need to quickly unscrew the pump and replace the valve cap. It's not the most elegant solution.
The Beautyrest air mattress has the same hot dog pack design as the Bestway air bed and the precarious feeling of floating in a pool. (Many companies that make air mattresses also make inflatable pools and accessories.
Note that it may not be the best air mattress for you if you are tall. Simmons lists its dimensions at 80 x 60 x 17 inches, but my measurements put it closer to 76 inches long, which means anyone taller than 6 feet will likely hang from the end. The mattress is made of a softer type of vinyl than others, making it easy to roll up and fold into a compact form for storage.
Bestway air mattress: The epitome of a cheap air mattress, the Bestway air bed is compact, lightweight and inflates relatively quickly with its integrated pump.
On the downside, this air mattress is only available in one size and is not comfortable at all. It sits low to the ground at 12 inches high, and the pump isn't powerful enough to fully inflate it, so it makes for a pretty jerky ride. The tubular design gives it the appearance of a pack of hot dogs, and the raised, horizontal hot dog that's meant to approximate the pillow support places the mattress upside down, making it more unstable.
The Bestway Air Bed has many negative reviews on Walmart.com citing slow air leaks, fast air leaks, torn seams, spontaneous bubbling, and terrible customer service (as well as dozens of very positive reviews). While Bestway's comically vague manufacturer's warranty doesn't inspire confidence, warranty isn't a key consideration here given the price. However, Walmart's policy states that most products can be returned in their original packaging for a full refund within 90 days.
