Mainstays is Walmart's private label, so yes Walmart owns the Mainstays furniture.

Mainstays brand furniture can be purchased from many retailers and online stores. Some examples of stores that sell the Mainstays brand include Walmart and Shop411.

Mainstays products are sold through Walmart. Walmart customer service may be able to help you find parts for your Mainstays patio swing. If you have the model number for your swing you can also get parts by contacting Courtyard Creations.

I have a Mainstays Vineyard Gazebo with glass shelf. I purchased the floor model without instructions. I need them

I'm trying to find this out. Correction though, Walmart does not "manufacture" Mainstays iron skillets or anything else for that matter.
