Difference between sites?

I just wanted to get some clarification on the difference between these sites since it says both are owned by APM.

I ordered some 2" talalay foam layers from the second site and haven’t heard anything back yet so I wanted to make sure there weren’t any issues at all.

The DIY site is specifically for those DIYers out there. The mattresses.net site is the full site with all our products and services listed including our pre configured models

That’s great, I just wanted to make sure there wasn’t a difference in the quality of materials/products being offered on one site versus the other.

Nope, same stuff on both sites.
