What Is It?


Bumps are sudden expansion, curved or round swell of a spot. They don’t happen naturally but are caused by an effect of something. As a result, it protrudes and becomes outwardly bulgy.

Air Mattress

An air mattress is also called a blow-up bed, an airbed, or a water toy. It is a kind of mattress which is produced with plastic or rubber. You can inflate it by pumping air into it through its valve, either with a manual or electric pump.

However, some air mattresses automatically inflate themselves when you open the valve. They are extremely helpful in guest rooms, or camping. This is because they’re very light and provide temporary beddings whenever necessary.

Not for kids

However, parents are warned not to allow their babies to lie on it. It can suffocate young children (those below one year), even though an air mattress is soft and tender to the skin. Also, the material, Phthalate plasticizers used in manufacturing air mattresses, is not safe for kids. They are poisonous and can cause health issues in children.

Narrow airbeds are more popular

People mostly go for narrow air mattresses because they don’t consume much space when storing or using them. Moreover, you can get a brand without the harmful Phthalate plasticizers or any chemical that can cause allergy to children’s skin. So if you are expecting visitors, and you don’t have enough space for a bed at home, go for the narrow air mattress.

Getting a lightweight narrow air mattress is a smart decision because while being small, it’s easier to inflate or carry. Also, you can take them neatly into a duffel bag. It is soft-locked, comfortable, and some are even resistant to water. Cool, right?

  • Deflate and uncover all attachments on it. If the bumps are many, start with the biggest one first. Remember that to avoid tearing your mattress, you should apply light pressure to it. Repeat this step if you have a lot of bumps in your mattress.
  • Try to open the valve a little for air to escape, but not all. It should be done in some cases where there are still bumps. The bump will disappear, but all the air won’t escape.
  • After the above step, you can pump more air into the mattress appropriately with an air pump. Manual or electric pumps can assist in pumping your mattress. Carefully place your hand on the mattress to check if you’re comfortable with the firmness or softness.

Note: Repeat the previous step if you notice that your mattress still has a bump.

You should cover the valve so that the air would not leak out. Check the valve for leakage to avoid deflation while sleeping on it.

These little air pockets make the bumps as you see them. Despite the bumps, they are still the perfect mattresses for hangouts and sleepovers, especially for camping. Most of all, these mattresses are easy to maintain and store since they’re foldable. So, if you’re planning to get one, no worries, it’s absolutely okay to have bumps. These bumps don’t hamper the integrity of the mattress.
