Serta Perfect Sleeper 14" Air Mattress, Queen

Pretty good reviews (4.4 out of 5.0) over at Walmart.com

I don’t think thats the same mattress. this says it has an external pump not an internal pump. I cant find this particular model!

Here we go, it’s this one. slightly less good reviews! people say the valve doesn’t hold air very well and you have to consistenty top up.
