A self inflating air mattress can be a boon or bane. The basic functioning of the self inflating air mattress is that you simply pump air into it and it inflates and remains in that state till it is deflated. But the major problem with these types of air mattresses is that they cannot retain the air for long.
One of the self inflating air mattresses is Eddie Bauer self inflating air mattress, available on the internet for nearly $40 USD. When you purchase it, it works fine the first time. Once you follow the detailed instructions, you can get it set within no time. If you are an expert, you need not even refer to the instructions. All you need to do is that blow up the Eddie Bauer self inflating air mattress, close the air valves and go off to sleep. In the beginning, it seems like an exciting alternative to the old manual one, though priced more.
When you go out camping, you are expected to be on the move constantly. You would expect that with a self inflating air mattress, you can move around easily. All that you need to do is place the sleeping bag over the mattress on the hard ground and sleep.
But the Eddie Bauer self inflating air mattress shatters any illusion you have about it. From the next use, the bag becomes nearly flat. Your lower limbs touch the ground. After successive usage it keeps on getting flatter till after 5th or 6th use, you are on the ground.
Most likely, the seams of the Eddie Bauer self inflating air mattress are quite weak. Hence this could be the reason why it keeps on getting deflated after regular use. Avoid the Eddie Bauer self inflating air mattress and maybe try your luck with other brands of self inflating air mattresses.
