Mainstays 6 in Twin Innerspring Mattress vs NapQueen Rainbow 5" Twin Memory Foam Mattress

Buy the Mainstays if you need a firm, low-profile twin for a bunk, trundle or guest bed and prefer springs under you. Buy the NapQueen if you want a softer memory-foam feel, motion isolation and a washable removable cover. The Mainstays is 6 inches of innerspring with a gel foam top and a 4.2 rating from far more owners; the NapQueen is 5 inches of memory foam with a slightly higher 4.3 rating from fewer owners. Both are budget twin-in-a-box mattresses, so expect a short lifespan and a firm-to-medium feel rather than deep cushioning.

• Choose the Mainstays if you want a firm innerspring twin that fits a bunk or trundle and holds up better for heavier sleepers.
• Choose the NapQueen if you want a medium memory-foam twin with motion isolation and a removable, machine-washable cover.
