Why do mattresses need to expand?

Due to the way bed-in-a-box mattresses are shipped, the normally need a few days to decompress and expand.

Zinus mattresses take 48-72 hours to expand fully, but are fine to sleep on the first night. Some customers have reported that it took up to a week to fully decompress, so don't freak out if it takes a few extras to expand.

Zinus encourages jumping, walking, and sleeping on your mattress when you get it. It actually helps with decompression!

Zinus's Cooling Green Tea mattress contours to your body, and provides a comforting, hugging feeling. The gel-infused memory foam makes the mattress cool to the touch. The soft, Poly Jacquard cover is smooth and breathable.

We found the Cooling Green Tea mattress soft and inviting. We rank it 6/10 on our firmness scale. We recommend this bed for side sleepers.

Reasons to Buy a Cooling Green Tea Mattress

  1. Zinus's Cooling Green Tea mattress keeps very cool. If you're a hot sleeper, you'll enjoy special features such as gel infused foam that dissipates heat. The top layer of gel foam contours to your shape and resists body heat to regulate your temperature all through the night.
  2. Enjoy this more natural mattress. BioFoam® with natural ingredients like green tea extract, castor natural seed oil, and all-natural charcoal help absorb moisture and keep your mattress smelling fresh.
  3. Side sleepers are able to enjoy the hugging, and cradling feeling of the foam. It provides them with the additional support they require.

Reasons to Avoid a Cooling Green Tea Mattress

  1. If you're a stomach sleeper, you'll do better with a hybrid or innerspring mattress. Foam mattresses won't provide you with the hip and shoulder support you need.

How To Choose The Right Mattress

First off, if your current mattress is 7-10 years old and you're experiencing more body aches and pains, it's time to buy a new mattress. Getting a good night's sleep is essential in maintaining a healthy body and mind. Choosing the right mattress doesn't have to be a hassle, follow these guidelines to find the right one for you!

  • Choose a mattress based on your individual needs. If you're looking for plushier support that adapts to your body's shape, a memory foam mattress is the best choice. If you want a more firm, traditional, feel an innerspring mattress is what you want. For the best of both worlds, get a hybrid mattress.
  • Get proper lumbar support. The majority of your body weight is positioned in what is called the "center third" of the mattress. Find a mattress that has excellent lumbar support as it prevents and alleviates pain in the back and hips. If you're looking for extra support, Saatva's unique lumbar zone technology might be the best fit.
  • Find a mattress with a long in-home trial. You want to be able to test your mattress over an extended period of time to really make sure this is the right one for you. Look for a company that offers a risk-free in-home sleep trial. Nectar offers a 365-day trial. IDLE Sleep offers a full 18-month trial (the longest in the industry).
