with my local stores qouting $160 and up, I wonder if I should grab these ($65-90) anyhow?

inner spring is different than foam.
Various material used for inner springs.
various quality of materials covering inner springs.


Better quality may last longer.
Bedwetting makes you want to dump the mattress before the very last legs of a very good mattress.
Some padding and inner springs make a more comfortable mattress.


For a kid maybe I'd get B011397784.
But I bought and paid locally.

Thanks. the prices I was quoted are for their cheapest innerspring, though probably considerably better than these.
talking for a small child, so yeah, bed-wetting will be more of a concern than insufficient support.

care to explain what is the specific ma'alah of the B011397784?

It looked like the padding was better than the other 2 inner spring mattresses you listed. and has a 10 year warranty.
But I see now that  B00HZNVFC2 also sounds good. 
I guess it's pot luck. Read reviews.  Sometimes they help.
