It is very comfortable to sleep on as long as it holds its shape. Here the good things end...
After a while, it started losing air. I found a hole in the seam, I closed it with glue, after a while, another hole in another place, again in the seam. Again glue, after a while... the same, in total I glued around 10 holes. After a few months, it started losing its shape, it became like a balloon. I bought the same new one. Exactly the same story as the first one.... If I see the other reviews, it's a matter of luck to get a piece that doesn't lose air. The bad thing is that there is no other high-quality option on the market that doesn't lose air...
6/23/2024: Since it was not working with the 'balloon', I went and bought a new one, the same. The third...

It must be a newer version, it has a different pump shape. I have it now for two months and, it has not let us down. I have inflated it, except for the first time, only 2 times a little, and it holds the pressure steadily!!
Of course, I learned from the mistakes in the first two, I take care of it very much, no abuse, only for SLEEP.. ;)
I don't sit on the edge to avoid sagging, I pay attention to how I sit and how I get up. No strong local pressure like elbow and knee. Knock on wood... it got 2 stars up.

Inflatable mattresses were my choice for a quick hosting solution instead of bunk beds.

The positives were:
- They didn't take up space and were lighter compared to bunk beds.
The negatives were:
- They squeaked or made a bouncing noise for anyone who slept on them.
- It was very easy for someone to fall off when they went to the edge.

I made this introduction because this specific mattress has nothing to do with any inflatable mattress I had tried in the past.

The positives of this specific mattress with Fiber-Tech technology are:
- It provides perfect support and relaxes the body during sleep.
- It inflates in 3 minutes and in no time, you have a ready bed.
- It is lightweight and can be stored quickly and easily anywhere.
- You can take it with you to have your own mattress wherever you are hosted.
- You can make use of 100% of the mattress surface as it has ideal support.
- It has a built-in pump, so you just plug it in and it's done (without carrying many additional accessories).
- You don't sweat during the summer months.
- It can be washed and cleaned relatively easily.
- It doesn't collect dust mites.
- It has a convenient height from the ground.

The negatives are:
- If you have tiles on the floor and it's winter, you definitely need a rug underneath because it transfers the cold from the tiles. However, in the summer, it is more than ideal!
- In my attempt to find another negative, I thought of mentioning that once a week you need to add a little air, but this doesn't significantly affect its stability.

For me, it is a smart purchase and I only have positive things to say about mattresses with Fiber-Tech support technology.
