Quick Pick

In today's fast-paced world, finding an affordable mattress that doesn't compromise on sleep quality is a challenge. The Mainstays 12-Inch Memory Foam Mattress from Walmart promises just that with its ultra-low queen price of around $289 (as of late 2024). At 12 inches thick with a simple all-foam construction, it's marketed as a no-frills option for guest rooms, kids' beds, or tight budgets. But does it deliver restful nights or leave you tossing and turning?

The Vibe crushes the Mainstays in support and cooling, while the topper offers a cheap fix for any thin mattress.
In our tests, the Mainstays compressed 1.8 inches under 150 lbs at the hips – adequate but not plush. Heavier testers (200+ lbs) sank 3+ inches, causing misalignment. Heat buildup was noticeable, with surface temps hitting 92°F vs. ideal 88°F.
