FAQ:

Q: How do mainstays mattresses arrive?

A: Mainstays mattresses will arrive at your door compressed and rolled up in a box. Once you remove your mattress from the packaging allow 48 hours for it to fully decompress. Mainstays is available in the following standard sizes: It’s available in 6″, 10″, and 12″ profiles. Prices vary depending on which height you choose.

Q: Is mainstays memory foam mattress good?

A: The 10″ version of the Mainstays memory foam mattress currently has a 4.0/5 star rating on Walmart.com. This review is based on 81 customer reviews. Consumers praised the brand for its light weight, softness, and comfort. They disliked it because it didn’t fully inflate in some cases, for being too hard, and for not conforming to their body.

Q: Are mainstays good for side sleepers?

A: We rate Mainstays as being a medium level of firmness. Medium memory foam mattresses are best for side sleepers and for combination sleepers (people who rotate between different sleeping positions throughout the night). The memory foam did a decent job of conforming to my body shape, but there are much better options out there.

Q: Are bed-in-a-box mattresses better than mainstays?

A: Even though the bed-in-a-box industry claims that they’re reducing costs by sending the package directly to your front door, these mattresses still routinely cost more than $1000. Those eye-popping prices make Mainstays mattresses seem much more appealing in comparison.
