Is this mattress good for side sleepers?

Mostly no. It is a firm tight top, and side sleepers usually want more cushioning at the shoulder and hip. A mattress topper can soften it.

Does it need a box spring?

No. It works on a platform bed, adjustable base or a box spring. Serta recommends a sturdy foundation to keep the warranty valid.

Use deep-pocket queen sheets rated for 13 to 15 inches. Standard 12-inch sheets will pull off the corners.

Yes. That Walmart price as of November 8, 2026 is low for a 13-inch zoned-coil queen from a major brand. Firm queens from Serta often sell for more.

The Perfect Sleeper adds more foam and cooling features at a higher price. The Clarks Hill Elite is the simpler, firmer budget option.

The mattress only. Foundation, box spring and frame are sold separately.
