Zinus Green Tea Mattress: In-Depth Review


The Quick Takeaway:

Overall, the Zinus Green Tea Memory Foam Mattress is an excellent value for money, comfort, and support. The unique green tea and castor seed oil infusion effectively minimizes off-gassing odors, which is a common concern with memory foam mattresses.

There are complaints about heat retention and firmness levels, with some customers finding the mattress too firm for their liking. Concerns regarding durability, with reports of sagging and indentations over time, and issues with full expansion after unboxing, have also been mentioned (Our testers did not experience any of those issues).



What Positive Reviews Say:

– COMFORTABLE & SUPPORTIVE – Many customers appreciate the balance of comfort and support offered by the mattress. The memory foam conforms to the body, which helps reduce pressure point pain, making it particularly popular among side sleepers.

– GREAT VALUE FOR THE MONEY: Given its price point, customers believe the mattress offers excellent value for money. They praise its comfort level and quality, which they feel rivals more expensive brands.

MINIMAL ODOR: The green tea and castor seed oil infusion help combat the off-gassing odor associated with many memory foam mattresses. Many customers confirm this feature, noting that the mattress had little to no smell upon unboxing.

Who It’s Right For

The Zinus Green Tea Memory Foam Mattress could be a good fit for:

  • Budget-Conscious Shoppers
  • Memory foam lovers
  • People Concerned About Off-Gassing


What the negative reviews say:

SLEEPS HOT: Some customers found the mattress tends to retain heat, making it uncomfortable during warmer months. This is a common issue with many memory foam mattresses.

FIRMNESS LEVEL: While the mattress is advertised as medium-firm, several customers found it to be on the firmer side. Firmness is highly subjective, so this could be a disadvantage for users who prefer a softer feel.

DURABILITY: Some customers reported sagging or indentation issues after a few months of use, raising concerns about the long-term durability of the product.

DID NOT FULLY EXPAND: A few customers complained that the mattress didn’t fully expand to the expected thickness after unboxing. This is likely due to the fact that it was kept compressed in the box at their home or in the warehouse for too long.

Who It’s Not Right For

The Zinus Green Tea Memory Foam Mattress might not be suitable for:

  • Hot Sleepers
  • Those Preferring a Soft Mattress
  • Long-Term Durability Seekers


The mattress effectively expanded to its full 12″ thickness.
Soft luxurious cover with breathable and cooling fabric. Easily unzips for cleaning and washing.
