Hi there - I ordered a Nectar mattress and mattress foundation because I thought I couldn't use my old foundation. The movers let me know I could use my foundation so I didn't need use the Nectar foundation.
I have the Nectar Queen size mattress foundation for sale (color is dark charcoal). It is still in the box and unused. Will discount if can pick up by end of weekend 11/3.
