This mattress is perfect for a daybed or trundle. Arrive in perfect condition and "inflated" immediately. Nice top cover and waterproof bottom side. Fairly comfortable and a good bargain for the price. I bought a $159 version of the same type of mattress at the same time, thinking it would be better support since it was being used daily,  and it was in no way as good as this one. The $159 model is going back and I am ordering another one of these.
