Product information

Experience the ZenBloks® Difference

ZenBloks® products are built with high-density, high-quality materials engineered for structure, comfort and long-term durability. Every component—from our extra-thick TPE gel to our premium memory foam—goes through repeated density checks, airflow testing and real-world use simulations to deliver ergonomic comfort that stays consistent day after day.

Extra-Thick TPE Gel (For Gel Seat Cushions)

ZenBloks® TPE (Thermoplastic Elastomer) gel blends flexibility, resilience and cooling airflow in a single material. Our extra-thick gel layer creates a stable sitting surface designed for long sessions at a desk, in a vehicle or at home. The open-grid honeycomb pattern increases ventilation while maintaining a firm, balanced feel.

Benefits of our extra-thick TPE gel cushion design:

  1. Balanced, even sitting surface: The gel grid adapts to your natural posture to support steady, comfortable sitting.
  2. High-density durability: Engineered to maintain structure, the gel resists flattening and sagging through daily use.
  3. Structured firmness: Offers a supportive feel without excess softness, helping promote a consistent upright sitting posture.
  4. Cooling airflow: The hexagonal honeycomb design enhances ventilation to keep the seating surface comfortable.
  5. Versatile applications: Works well on office chairs, car seats, trucks, gaming setups and home seating.

High-Density Memory Foam (For Pillows & Leg Elevation Wedge)

ZenBloks® memory foam is a premium, high-density polyurethane foam engineered for structured support and long-lasting performance. Its viscoelastic response allows the foam to gently adapt to your natural shape and return to form after each use, helping create a balanced, stable resting experience.

Key characteristics of ZenBloks® memory foam:

  1. Adaptive contouring: The foam responds to pressure and warmth, creating a supportive, personalized surface feel.
  2. Even weight distribution: Helps promote a balanced resting posture by naturally adapting to your shape.
  3. Steady, slow-response feel: The foam gradually returns to its original structure, providing smooth, stable movement.
  4. High-density resilience: Engineered to resist compression and maintain shape through repeated daily use.
  5. Enhanced comfort vs. standard foam: Offers a more adaptive, body-responsive feel than traditional polyurethane foam.

Memory foam and standard polyurethane foam both offer long-term durability, but memory foam provides a more structured, contouring experience while standard foam feels more springy and immediate.

ZenBloks Official Policy: Returns, Exchanges & Warranty

Our Commitment to Quality: At ZenBloks, we design premium products built for lasting comfort and support. The policy below is written to be clear and practical so you know exactly what to expect when you order from us.

Contact Information:

  • Customer Support: Contact ZenBloks Support

  • Business Address: 1600 Rosecrans Avenue, Suite 400, Manhattan Beach, CA 90266

  • Return shipping details and the nearest warehouse return address will be provided once a return request has been approved and initiated through our support team.

Before Opening Your Product

ZenBloks products arrive vacuum-sealed to protect the foam during transit. Once the seal is opened, the foam expands permanently and cannot be re-compressed or re-sealed. Because of this, returns are only accepted for items that remain unopened and unused. 

Before opening the packaging, please take a moment to:

  • Verify the item, size, and color on the label match your order confirmation.
  • Inspect the outer packaging for visible damage that may have occurred in transit.

F.A.Q.

Common question about our products

What is memory foam and how does it differ from regular foam?

Memory Foam:
Memory foam, originally developed by NASA in the 1960s, is a type of polyurethane foam known for its viscoelastic properties. This means that memory foam is both viscous (slow-moving and thick) and elastic. These properties allow the foam to contour closely to the shape of an object pressing into it and then slowly return to its original shape once the pressure is removed. The main characteristics of memory foam include:

  1. Temperature Sensitivity: Memory foam softens with heat, which means it becomes more pliable with body heat, allowing it to mold to the body's shape. This provides personalized contouring and even weight distribution.
  2. Pressure Point Relief: Due to its ability to contour, memory foam can distribute weight evenly, which can reduce pressure on certain areas of the body, such as hips and shoulders when sleeping.
  3. Slow Response Time: After pressure is removed, memory foam takes a bit of time to return to its original shape, which is why it's often described as having a "sinking in" feeling.

    Differences:
  4. Feel: Memory foam offers a contouring, sinking feel, whereas regular foam feels more bouncy and resilient.
  5. Heat Retention: Memory foam tends to retain more heat compared to regular foam due to its denser structure.
  6. Conforming Ability: Memory foam provides better contouring and pressure point relief compared to regular foam.
  7. Durability: High-density memory foam often lasts longer and resists sagging more than low-density regular foam.
  8. Price: Memory foam is generally more expensive than regular foam because of its specialized properties and manufacturing process.

In summary, while both memory foam and regular foam are derived from polyurethane, they possess distinct properties and offer different experiences. Memory foam is known for its contouring and pressure-relieving abilities, while regular foam is more resilient and bouncy.

What are the benefits of using a memory foam pillow?

Memory foam pillows have gained popularity over the years for a variety of reasons. Here are some potential benefits of using a memory foam pillow, without making medical claims:

  1. Contouring Support: Memory foam pillows mold to the shape of your head and neck, providing tailored support that can help with maintaining natural alignment.
  2. Pressure Point Relief: The viscoelastic nature of memory foam distributes weight evenly, which can help with alleviating pressure on certain areas, offering a more comfortable sleep experience.
  3. Reduced Motion Transfer: If you share a bed, the properties of memory foam can help with reducing movement transfer. This means if one person moves or gets up, the other person is less likely to be disturbed.
  4. Durability: Memory foam pillows tend to retain their shape for a longer time compared to traditional pillows, reducing the need for frequent replacements.
  5. Hypoallergenic Properties: Memory foam is known to be resistant to allergens which can be beneficial for those with sensitivities or allergies.
  6. Consistent Comfort: Unlike feather or down pillows, which might need regular fluffing, memory foam pillows consistently hold their shape, offering a stable level of comfort and support night after night.
  7. Adaptable to Temperature: Memory foam responds to body temperature, softening with warmth and providing a cozy feeling during colder nights.

Remember, while many people enjoy the benefits of memory foam pillows, individual preferences and experiences can vary. It's always a good idea to test a pillow to determine if it's the right fit for your personal comfort needs.

Do memory foam pillows have an odor, and how long does it last?

ZenBlok memory foam pillows may have a slight odor initially due to the manufacturing process, but it is harmless and dissipates within a few days. We use high-quality, CertiPUR-US certified memory foam to minimize any potential odor.

How does a memory foam pillow help with neck pain and alignment?

Memory foam pillows can aid in alleviating neck pain and promoting proper spinal alignment for several reasons:

  1. Contouring Support: Memory foam is viscoelastic, meaning it responds to both temperature and pressure. When you lay your head and neck on it, the foam gently molds to the contours of your body. This provides tailored support, ensuring that the neck and head are cradled uniformly, reducing pressure points.
  2. Proper Alignment: Traditional pillows might either elevate the head too much or provide insufficient support, causing the neck to align improperly with the spine. A contour memory foam pillow can offer the right amount of loft and support to keep the cervical spine (neck region) in a neutral position, aligning it with the rest of the spine.
  3. Consistent Support: Unlike other materials that might sag or lose shape over time, Zen Bloks memory foam retains its shape while still offering consistent support throughout the night. This means fewer adjustments and less potential for waking up in an awkward, strain-inducing position.
  4. Distribution of Weight: Memory foam spreads the weight of the head and neck evenly across its surface. This even distribution can reduce the strain on any specific area of the neck.
  5. Reduced Muscle Tension: By offering optimal support and alignment, memory foam pillows can help relax the muscles around the neck and shoulders, reducing tension and discomfort.

However, it's essential to note that while memory foam pillows can offer several benefits for neck pain and alignment, individual preferences and needs can vary. It's always a good idea to consult with a healthcare professional or physical therapist to ensure that you're making the best choice for your specific situation.

What is the ideal user height for the Leg Elevation Wedge, and what are its benefits?

Our High-Density Memory Foam Leg Elevation Wedge is ideally crafted for individuals ranging in height from 5'8" to 6'4". It serves as an ergonomic aid for those seeking relief from lower back decompression, hip, sciatica, and pelvis pain. Sizes measuring 21 x 21 x 10 or 11 inch heights, this generously sized wedge is designed to enhance circulation and provide support, offering relief from the discomfort associated with prolonged periods of sitting or standing.

How does the Leg Elevation Wedge promote lower back relaxation?

The wedge is engineered with precision—each curve and angle is shaped to naturally elevate your thighs and hamstrings while allowing your knees to rest gently along the ergonomically designed curve. This subtle downward angle for your calves creates a gentle traction that encourages spine decompression and blood flow, aiding in the relaxation of the pelvis, lower, and mid-back areas.

Can the Leg Elevation Wedge be used for overall body rejuvenation?

Absolutely. Our wedge is constructed from high-density foam robust enough to support legs comfortably in a relaxed, natural position. It's an excellent tool for aiding in lower spine compression, alleviating pain in various areas, and facilitating overall body relaxation. For optimal results, we recommend using it for 20-30 minutes before sleep.

Is the wedge easy to move and use around the house?

Yes, designed with convenience in mind, our lightweight and versatile bolster comes with side handles for easy transportation. Whether you're in bed, on the sofa, or using a floor mat, our Zen Bloks Luxury Leg Elevation Bolster Wedge can be effortlessly moved to your desired location, adding a touch of sophistication to any room with its elegant white color cover.

Are memory foam pillows suitable for all sleeping positions?

Memory foam pillows are designed to accommodate a range of sleeping positions due to their adaptive and contouring nature. However, the suitability of a memory foam pillow often depends on its height (loft) and firmness, as well as the specific needs of the sleeper. Here's a breakdown by sleeping position:

  1. Back Sleepers: Memory foam pillows can be especially beneficial for back sleepers as they cradle the head and support the natural curve of the neck. A medium loft 5.4" like Zen Bloks pillows and firmness are typically preferred by most back sleepers to ensure proper alignment.
  2. Side Sleepers: Side sleepers often require a higher loft 5.4 inches like Zen Bloks Cervical pillows to fill the gap between the shoulder and neck, ensuring the neck is aligned with the spine. Memory foam pillows can contour to this area, providing the necessary support and pressure relief.
  3. Stomach Sleepers: Stomach sleepers usually need a lower loft around 4.1 inches like Zen Bloks dual sided pillow (all models) to prevent their neck from arching backward, which can lead to strain. A thinner, softer memory foam pillow might be more suitable for stomach sleepers to maintain a neutral neck position.
  4. Combination Sleepers: Those who shift between positions throughout the night can benefit from a memory foam pillow with a medium loft and firmness. The adaptive nature of memory foam can adjust to the changes in position, offering consistent support.

While memory foam pillows offer versatility for various sleeping positions, it's essential to choose a pillow that feels comfortable and supports individual needs. Some brands also offer adjustable memory foam pillows, where users can add or remove foam to achieve their desired loft and firmness, making them suitable for a broader range of sleepers.

What are the benefits of TPE Gel and why use it for seat cushions?

Extra Thick TPE Gel:

Zen Bloks TPE (Thermoplastic Elastomers) gel is a type of flexible, durable, and moldable material that has properties of both plastic and rubber. "Extra thick" indicates a denser concentration or greater volume of this material in a particular product, offering more cushioning and resilience.

Benefits of Sitting on a 2-inch Gel Seat Cushion Made from Extra Thick TPE Gel with Hexagonal Shape:

  1. Enhanced Comfort: The 2-inch Zen Bloks gel seat cushion thickness, especially when made from extra thick TPE gel cushion, provides an optimal level of cushioning that helps reduce pressure points on the buttocks and thighs. This means you can sit for extended periods without experiencing discomfort.
  2. Improved Blood Flow: The hexagonal shape and design promote better distribution of body weight. By ensuring an even spread of pressure and reducing pressure points, it encourages healthier circulation and blood flow, which can be crucial for long durations of sitting.
  3. Firm Support: While the TPE gel offers cushioning, its inherent properties also ensure it remains firm enough to provide the necessary support. This balance between cushioning and support is vital for maintaining good posture and avoiding back issues.
  4. Durability and Longevity: TPE gel is known for its resilience and ability to retain its shape over time, ensuring that the cushion doesn't flatten or deform easily even with regular use.
  5. Temperature Regulation: TPE gel has properties that allow it to remain cool, ensuring you don't experience heat build-up, which is common with prolonged sitting.
  6. Versatility: The gel seat cushion's design is adaptable for various seating surfaces, from office chairs to car seats, making it a versatile choice for those seeking comfort in different settings.

In summary, a Zen Bloks 2-inch gel seat cushion made from extra thick TPE gel, designed with a hexagonal shape, offers a unique combination of comfort, support, and durability, enhancing the sitting experience, especially for those who spend long hours seated.
