10 Inch vs 8 Inch Mattress Specs
Thickness and Height
The Zinus 10 Inch Green Tea Memory Foam Twin Mattress stands at 10 inches tall, while the Zinus 8-Inch Green Tea Memory Foam Mattress in Full size is 8 inches high. You get two extra inches of profile with the larger model. This difference affects how high the bed sits from the floor. Taller mattresses often make it easier to get in and out of bed, especially for taller individuals or those with mobility concerns. The 10-inch option provides more visual bulk and potentially more cushioning layers between you and the bed frame. The 8-inch version sits lower, which may suit platforms or slatted bases better. Your choice depends on whether you prefer a higher profile or a more grounded feel.
Mattress Construction Layers
Both mattresses use memory foam construction, but the layer breakdown differs. The 8-inch model explicitly lists its internal structure: 2 inches of conforming memory foam, 2 inches of soft, airflow-enhancing comfort foam, and 4 inches of durable, high-density base support foam. This three-layer design is detailed in the product data. The 10-inch Twin model does not provide a specific layer-by-layer breakdown in the provided specifications. It is described generally as green tea-infused memory foam with a soft poly jacquard cover. While both offer pressure relief, the 8-inch model gives you more transparency into how the support and comfort zones are distributed. The 10-inch model likely has similar materials but with less specified internal detail.
Size and Dimensions
You are comparing a Twin size against a Full size. The 10-inch Twin mattress measures 39 inches wide by 75 inches long. The 8-inch Full mattress is wider at 54 inches by 75 inches long. Both share the same length, but the Full width offers 15 more inches of sleeping surface. This makes the 8-inch model significantly wider, suitable for couples or single sleepers who like extra space. The Twin is narrower, ideal for children, guests, or tight spaces. If you need width, the 8-inch Full is the clear choice. If space is limited, the Twin fits smaller rooms. The height difference remains, with the Twin being taller despite being narrower.
Certification and Safety
Both mattresses share the same CertiPUR-US certification. This standard ensures the foam is made without ozone depleters, PBDEs, TDCPP or TCEP flame retardants, mercury, lead, and other heavy metals. It also verifies low VOC emissions for indoor air quality. This certification applies to both the 10-inch Twin and the 8-inch Full models. You get the same assurance of durability, performance, and content safety regardless of which thickness or size you choose. The green tea and activated charcoal infusion is present in both, aimed at keeping the mattress fresh. There is no difference in safety standards or material certifications between these two specific SKUs.
Cover Material
The 10-inch Twin model specifies a soft poly jacquard cover. This fabric type is known for its textured, woven appearance and soft hand feel. The 8-inch Full model does not explicitly list the cover material in its key specs or features. It mentions the foam layers and the green tea infusion but leaves the outer fabric undefined in the provided data. If you have a preference for a specific cover texture or material, the 10-inch model gives you that information. The 8-inch model requires you to assume a similar cover or check further details. For now, the Twin offers more clarity on what touches your skin.
Which thickness fits your sleep style best
Side sleepers needing deep pressure relief
The 10-inch Twin model offers more foam depth to cushion your hips and shoulders. Its 10-inch height provides a higher profile that reduces the feeling of sinking to the bed frame. The green tea and ActivCharcoal infusion helps keep the surface fresh, while the CertiPUR-US certification ensures the foam meets strict safety standards for content and durability.
Average weight back sleepers
The 8-inch Full size is ideal for back sleepers who need firm support without excessive height. It features a 4-inch high-density base support foam that stabilizes your spine. The 2-inch comfort layer and 2-inch conforming memory foam cradle your shape effectively. This setup is designed to keep your body aligned while you rest on a slightly lower profile.
Sleepers wanting a lower bed height
If you prefer a mattress that sits closer to the floor, the 8-inch Full size is the practical choice. At 8 inches tall, it creates a lower center of gravity in the bedroom. The construction includes durable base support foam and pressure-relieving comfort layers. You get the same green tea scent and CertiPUR-US safety as the thicker version, just in a more compact form.

Frequently asked questions
Is a 10 inch mattress better for side sleepers?
Yes, the 10-inch profile offers more foam depth to cushion hips and shoulders effectively. The Zinus 10 Inch Green Tea Memory Foam Twin Mattress provides a higher sleep surface that reduces the feeling of sinking to the bed frame. This extra height allows for better pressure relief compared to thinner options.
Does the 8 inch mattress feel too firm?
The Zinus 8-Inch Green Tea Memory Foam Mattress in Full size provides a dense, supportive base suitable for average-weight back sleepers. While it is thinner, the memory foam construction still offers contouring. You get a firmer feel due to the reduced height, which some prefer for spinal alignment.
What is the weight difference between the two models?
The 10-inch Twin model weighs 32.6 pounds, while the 8-inch Full model weighs 36.7 pounds. The Full size is heavier despite being shorter because it covers a larger surface area. You should consider this weight difference if you plan to move or rotate the mattress frequently.
Do both mattresses have the same scent additives?
Yes, both models are infused with green tea and activated charcoal. These additives are included to help maintain freshness in the foam. You get the same olfactory benefits regardless of whether you choose the 10-inch Twin or the 8-inch Full size for your bedroom.
Which size is better for a small guest room?
The 10-inch Twin mattress measures 39 inches wide and 75 inches long, making it ideal for compact spaces. Its lower weight of 32.6 pounds also makes it easier to maneuver through narrow hallways. You get a comfortable sleep surface without taking up excessive floor space.
Is the 8 inch model suitable for couples?
The 8-inch Full size measures 54 inches wide, providing more width than a Twin but less than a Queen. It is best for average-weight back sleepers or single adults who want more room. Couples may find the Full size snug, so the 10-inch Twin is not suitable for two people.
