Sleep Position Ratings
Zinus Mattress
Ratings for the Zinus Green Tea Mattress vary based on the thickness chosen. The 6″ and 8″ models received the highest ratings from our sleepers over 230 pounds, while the 10″ and 12″ models performed better for our light and average weight sleep testers. Heavier testers, particularly stomach sleepers, found those models to be too soft and body conforming to provide adequate support.
Overall, the mattress served our light-and average-weight back sleepers the best across most mattress thickness options. These testers found that the memory foam provided good pressure point relief with the right amount of cushioning around the hips and shoulders.
Casper Mattress
The Casper best suited people under 230 pounds, all of whom gave the model positive reviews for motion isolation and pressure relief, regardless of their individual sleep styles. While heavier side sleepers found the Casper adequate, back and stomach sleepers over 230 pounds experienced some excess sagging and reduced spinal support.
All of our testers appreciated the model’s temperature neutrality and breathability, which they felt set it apart from similar foam mattresses. They also noted that the Casper offers an exceptionally quiet sleep experience, thanks to its all-foam construction.

How Is the Zinus Built?
The Zinus comes in four thicknesses: 6 inch, 8 inch, 10 inch, and 12 inch. Each thickness profile corresponds with a different respective firmness level: firm (8), firm (7), medium firm (6), and medium (5). Regardless of thickness or firmness level, the Zinus’ all-foam construction offers better body-conforming pressure relief and motion isolation than most innerspring mattresses.
While the 6-inch design consists of a 1-inch memory foam comfort layer over a 5-inch HD support core, the other designs each feature a comfort layer consisting of a 2-inch polyfoam layer under another layer of memory foam. The 8-inch, 10-inch, and 12-inch versions include, respectively, 2-inch, 2.5-inch, and 3-inch memory foam layers. All designs feature a jacquard knit cover.
How Is the Casper Built?
The Casper’s cover is made of a blend of recycled polyester, polyester, upcycled cotton, rayon, and lycra. Each cover contains material made from up to 45 recycled water bottles. At 11 inches, the medium (5) Casper is relatively thick, compared to other all-foam mattresses. The model’s two comfort layers consist of one responsive 1.5-inch layer of polyfoam and a softer 2-inch layer of zoned 4 PCF memory foam. This combination of materials gives the Casper some bounce without reducing its pressure-relieving qualities.
Made from 7 inches of 1.8 PCF polyfoam, the Casper’s support layer provides additional stability. The high-density material helps reduce sagging in the parts of the mattress that bear the most weight.

Warranty
Zinus offers a 10-year warranty for all current mattresses. This warranty is entirely non-prorated. Warranty coverage begins on the date of purchase. Zinus will, at their sole option, repair or replace all mattresses that are deemed defective. Mattress owners will be responsible for all shipping and handling costs associated with having a mattress repaired or replaced. The warranty will be voided if the mattress is used with an electric blanket or heating pad.
The warranty will cover visible indentations or sagging in the sleep surface that measure one and a half inches (1 1/2″) or deeper. The warranty will not cover the following:
-
- Normal increases in foam softness that do not affect its pressure-relieving abilities, or visible indentations or sagging in the sleep surface that do not measure one and a half inches (1 1/2″) or deeper. These issues are all considered standard wear and tear.
- Burns, cuts, tears, stains, and other types of physical damage that occur due to owner misuse, improper cleaning, and/or inadequate foundational support.
- Damage to the mattress handles. Per Zinus: ‘[Handles] are to be used only for adjustment purposes and are not intended to lift, turn or transport the product.
This warranty is exclusively extended to original owners that purchase their mattress from Zinus or an authorized Zinus retailer. Anyone who buys or acquires the mattress from the original owner or a non-authorized retailer will not be eligible for warranty coverage.

Warranty
Casper offers a 10-year non-prorated warranty. Warranty coverage kicks in on the original mattress purchase date. During the warranty coverage period, Casper will replace or repair a defective mattress. Casper will cover fees for returning a defective mattress to the company, but the owner will be required to pay fees for having a replaced or repaired mattress shipped back to them. Mattress owners must pay the difference if their defective mattress is replaced with an upgrade model. In the event that a defective mattress is repaired or replaced with the same mattress model, the original warranty coverage will continue. If the mattress is replaced with an upgrade, then a new warranty will be issued beginning on the date that the upgrade is purchased.
The warranty will be voided if the owner does not provide a proper foundation to support the mattress. According to Casper, proper foundation options include the following: a foundation and modern box spring with wooden slats that are no more than 4 inches apart; a flat platform bed; or a slatted base made of wood with slats that are no more than 4 inches apart.
The warranty will cover body impressions in the sleep surface measuring 1 inch or deeper despite proper use and handling. The warranty also covers physical flaws that cause mattress materials to split or crack, and manufacturing defects associated with the mattress cover. The warranty does not cover impressions measuring less than 1 inch deep. Additional defects not covered under warranty include physical damage such as burns and stains, and comfort issues that arise due to normal wear and tear or changes in the owner’s mattress preferences.
The warranty is exclusively available to the original purchaser of the mattress. Anyone who purchases or acquires this mattress second-hand does so ‘as is’, and will not be eligible for warranty coverage.
