The mattress doesn’t fit on the base well. It’s too stiff to follow the base movements and shifts side to side on the base. The base should have guards preventing the mattress moving sideways.
You can’t beat the value for the level of quality you get with the bundle. The mattress is very comfortable and cools decently well. The adjustable base is a bit creaky but works fine.
It is comfortable but I have notice that the mattress does not bend same as the adjustable base does. On the other hand, it is too high so I will necessarily have to get a foot stool to get into the bed
