Overview

A 5 inch twin memory foam mattress from Zinus, built with green tea and charcoal infused foam over a base layer and a breathable knitted cover, rated medium firm.

At 5 inches thick, this sits at the thinner end of Zinus's foam mattress range, which points it toward a bunk bed, daybed, or guest room rather than a primary adult mattress needing deeper support layers. The green tea and charcoal infusion targets odor rather than firmness or support.

  • 5 inch profile, twin size
  • Medium firm feel
  • CertiPUR-US certified foam
  • OEKO-TEX Standard 100 certified cover

Who it's for

Fits a twin bed used by a child, guest, or in a bunk or trundle frame where a slimmer profile matters. Not the choice for a primary adult sleeper wanting a thicker mattress with more distinct support layers.

Pros and cons

Pros
  • Zoned support adapts to different sleep positions
  • Green tea and charcoal foam targets odor
  • CertiPUR-US and OEKO-TEX certified materials
  • Breathable knitted cover
Cons
  • 5 inch profile is thin for a primary adult mattress
  • Some off gassing smell expected for the first 1 to 2 days

Performance notes

Zoned pressure relief means different sections of the mattress respond to weight differently, so hips and shoulders get more give than the middle of the back regardless of sleep position. The knitted cover is designed to breathe rather than trap heat, and any factory smell from unboxing is expected to clear within 24 to 48 hours as the foam expands.
