Why Should You Buy This Product?
This is a great option for environmentally conscious consumers. The firmness and structure of the bed all contribute towards healthy posture and can help relieve back discomfort.[/su_note]
What To Look for Before You Buy?
Even if you have a list of solid recommendations, it always helps to know exactly which features you should be looking for when making a purchase. Thus, we will be giving you some pointers which will help you find the best product for you!
The first and most important choice to make while buying mattresses of any type is to determine what size you need. King size mattresses are best for those sharing beds and looking to have some wiggle room. It is also useful for those sharing beds with their children or pets.
A large air bed does not, by default, carry heavy loads. If the construction is poor, the seams might break, or the walls may simply burst. You may also see deformation in your mattress due to overload. Thus, it is important to know how many pounds the mattress you are considering will be able to take.
Beams and Coils
We recommend air mattresses that are equipped with high-quality beams and coils. Adding to the previous pointer, coils and beams will help distribute weight more evenly, thus allowing the mattress to handle the load better. They also help the mattress fight signs of wear due to overloading for longer.
Beams and coils also contribute to giving your back ample support, without which you may end up sleeping in unhealthy postures. By preventing the bed from sinking in, the beams help maintain a straight spine for better sleep and health.
How you expect to use the air mattress will also play a big role in making the perfect pick. Air mattresses can be used for regular or occasional indoor use and during camping trips as well. However, not all mattresses are built for the same purposes.
For outdoor use, you will need a mattress that has a really strong construction. The material needs to be puncture-proof (against branches, rocks, and such) as well as waterproof to combat rain and outdoor moisture. Outdoor mattresses should also come with high-quality carry bags to make transportation easier.
Lastly, outdoor mattresses should have the option for manual or external pumping. Indoor air mattresses also need to have specific features. They should have ample high-quality coils and beams that can distribute weight really well and prevent any deformation due to daily use.
Inflation and Deflation Time
You may also take into account how long the mattress takes to inflate and deflate. A long inflation time may not be a problem at home, but it becomes an inconvenience when you are out camping and not interested in spending time setting up.
