It inflates and deflates quickly with the internal pump....Good quality materials....Slightly squeaks with movement which I consider normal...Also, it needs air refilling every 3 days...I think it is top in its category

I have had it for about 2 weeks. It is used on a daily basis since the mattress I was sleeping on was terrible in the rented place. I bought it with some hesitation since I have no previous experience, but there was no other solution since it's not worth buying a new mattress for a season.
So far, I can say that it does its job, I sleep much better compared to before because I don't have springs poking my sides. It inflates and deflates quickly, it needs a little bit of air refill every 3-4 days, but that's the least of it.
Time will tell its durability and sleep comfort. Sometimes it feels like a water mattress, but personally, I prefer this over having my sides hurt from the springs.
The ONLY drawback I found was that even though it was mentioned in the specifications as 'carrying bag', I never found it in the packaging. Under different circumstances, I would return it, but I couldn't bear sleeping on the previous mattress anymore. And that's why not 5 stars

It inflates easily and quickly, I would recommend it, but it needs to be inflated every two days because it deflates a little

(Use on a sofa bed by one person)
Fine for the first month
Terrible for the second month
In the trash by the third month
Worth the money (about €0.50 per night) for around 65 nights of durability.
