Sleep Number Mattress 3 pc Outer Shell

Description

This is a queen sized Sleep Number Mattress Outer Shell
Model 7000 / i8
This is the complete 3 piece mattress outer shell/case that includes:
- Bottom section where the air chamber(s), foam rails, and foam divider go
- Middle section where the memory foam goes
- Top section which is a silky, pillow top that marketed as having cooling characteristics
I've always had a mattress cover on it so I can't attest to how/if the cooling really works
Although I've always had a mattress cover on it there is some signs discoloring.
Please note, this is just the 3 piece outer shell, it does NOT include the air chambers, pump or any other components.
