Most outdoor inflatable lounger designs do not require that you use any type of air pump to inflate the device. Many incorporate into their design, a quick and pump-free inflation technique, that ensures all you need is your inflatable air lounger.
Many will feature a design where you open a panel, which will inflate the tube as you drag it through the air. To seal, you simply close and then wrap the fabric down before securing it with a buckle. This design is the most common and convenient that you will see used in outdoor inflatable loungers.
Though it is important to note that while the vast majority have a pump-free design, there are some that you will need to purchase an air pump to inflate. It is best to look at the product description to ensure you are getting the design you want.
