NapQueen Rainbow 5" Twin Memory Foam Mattress vs Zinus 6 Inch Green Tea Cooling Gel Memory Foam

Both are budget memory-foam mattresses in a box, but they suit different sleepers. The NapQueen Rainbow is a thin 5-inch twin with a removable, machine-washable cover, which makes it the better pick for bunk beds, trundle beds and kids' rooms. The Zinus 6-inch Green Tea Cooling Gel is a touch thicker, adds gel and green tea infusions for hot sleepers, and carries a 10-year warranty, so it is the stronger choice for an adult's everyday bed. Owners of both report they soften over time; the Zinus holds up a little better for daily adult use.

• Choose the NapQueen Rainbow if you need a low-profile twin for a bunk or trundle bed, want a washable removable cover, and are buying for a kid or a guest room.
• Choose the Zinus 6 Inch Green Tea Cooling Gel if an adult will sleep on it nightly, you run warm at night, and you want the longer warranty and slightly thicker foam.
