How To Choose The Best King Mattress
Choosing the right best air mattress starts by knowing how you intend to use it – will it be for occasional overnight guests or will it be for exploring the great outdoors?
There are three factors that you need to consider no matter what size air mattress you are purchasing.
Type of Pump
Most air mattresses now come with their own pump whether that be a built-in one or a stand-alone one.
What you need to consider is how it is powered and the inflation time.
If you are planning on using your air mattress for camping then you need to make sure that you will either have access to an electric power outlet or that your pump cna be powered in an alternative way.
Ease of Storage
If you are planning to take your air mattress on your adventures then you need to ensure that the mattress can be easily stored.
Check the dimensions of it when it is deflated.
Many air mattresses now come with their own travel bag making them even more portable.
Ensuring that your mattress is up to your intended use means checking that all the materials are durable and strong.
Does it come with an anti-slip base meaning that it stays put and can also prevent it from any unnecessary damage?
What Types of Air mattresses are available?
You may have assumed that choosing an air mattress would be an easy decision, but did you know there is so much variety on the market?
There are air mattresses available to suit a variety of requirements.
From ones designed to fit across your car’s seats, to specific inflatable camping mattresses and even long-term air mattresses designed to relieve the pressure felt from traditional spring mattresses.
Knowing which mattress would benefit you best can be confusing, but this guide will help to explain the different types of air mattresses and who they suit best.
Foam mattress surfaces remain static meaning the weight placed on the air mattress is evenly distributed over a large surface area to keep the pressure low against your body.
Similar to the results from memory foam mattresses, it responds to the weight and level of movement whilst preventing soreness, tossing, and turning.
Hybrid air mattresses
Combine layers of foam plus the static support surface from the air pockets within to give you the best experience from both types of mattresses in a unique combination.
The majority of these hybrid mattresses still require a pump to inflate the alternating air pockets so you will still need access to mains power.
The foam interior provides comfort and distributes the pressure across your body.
These have a dynamic surface unlike foam mattresses and include a layer of air cells that alternate their inflation levels to suit your needed support and comfort.
The airflow section is controlled by a pump like most air mattresses and requires constant attachment to mains power.
As the airflow section inflates it provides support and the deflation provides relief and movement in the skin to encourage healthy blood flow and eliminate any health issues from the discomfort.
It can be difficult to find king-size inflatable mattresses on the market that are large enough to meet the name of “king-sized”.
As well as still providing you with all-over body comfort and support without causing movement, noise, or even dips in the mattress that could lead to some aches and pains.
We hope you’ve found something in this article that ticks all your boxes whether you plan on using your king-size inflatable mattress for use as a spare guest bed or even to take camping with you in the great outdoors.
