I purchased the Lost Horizon double size camping mattress. This product exceeded my expectations in almost every way.
First is the comfort. You would not expect a camping mattress to be extremely comfortable but this one is. It is like sleeping on a regular bed with a high quality mattress. The Lost Horizon mattress has a soft covering that is comfortable to lay on.
Next is the warmth. I have slept on air mattresses before and even when being used indoors, an air mattress gets cold. The Lost horizon mattress is insulated and it stays warm and comfortable all night.
Often, air mattresses will leak air very slowly during the night and become deflated. With the Lost Horizon mattress, it stayed air tight all night and was just as supportive and firm as when I first I went to bed.
The quality of this mattress if high for what you are paying. In my opinion it was well worth the price.
I purchased my mattress with the available rechargeable battery operated air pump which also seems to be very high quality. I found I didn't really need the air pump to setup the mattress, just a bit off air from the pump and the mattress was ready to go. The pump really came in handy when it was time to put the mattress away. You can use the pump to pull all the air from the mattress and get it as flat as possible for storage.
Overall great product, great value for the money, I would buy this product again.
