CORE SUPPORT

Comfort is a personal preference. Comfort of a mattress can vary from person to person based on size and weight distribution, along with sleeping position.

Lowering the body’s core temperature promotes a deeper, more rejuvenative sleep. Some mattresses are designed to be cooler throughout the night.

Conformance ensures the mattress adapts to your body shape, supporting natural alignment and reducing pressure points for better comfort.

Core support in a mattress ensures proper spinal alignment and distributes body weight evenly, enhancing comfort and reducing pressure points for a restful sleep.

SAFEGUARDING YOUR FAMILY

Mattress Type:

Not sure which mattress type is right for you? Here's a quick guide to help you choose the perfect fit:

Hybrid

Cool, responsive, and supportive
Hybrid mattresses combine cooling memory foam with a supportive coil system to offer a balanced feel with airflow, bounce, and comfort. They are a great choice for sleepers who prefer a cooler, more responsive surface.

Quilted Hybrid

Lux comfort with hybrid support
Quilted hybrid mattresses include all the benefits of the hybrid design, with the added softness of a quilted Euro top. They are ideal for those who want extra cushioning without giving up support.

All-Foam

Contouring and motion-absorbing
All-foam mattresses are made from premium memory foam that molds to the body and reduces motion transfer. They are best suited for sleepers who enjoy a more still, body-hugging feel.

Firmness levels from plush to firm

Not sure which firmness is right? Here’s a quick guide to help you choose the best mattress feel based on sleep style and comfort preferences.

Plush

Soft and pressure-relieving
Plush mattresses are well-suited for side and back sleepers. They gently cradle the body while still providing enough support for all-night comfort.

Medium

Balanced comfort and support
Medium mattresses are the most popular choice and are very versatile, working well for side, back, and combination sleepers. They offer a mix of softness and firmness to accommodate a wide range of sleep positions.

Firm

Stable and supportive
Firm mattresses support proper spinal alignment, especially for back and stomach sleepers. With a more solid feel, they are ideal for those who prefer sleeping on top of the mattress or need added support.

Flip flopping on the mattress

Was skeptical at first, but after the first night I was pleasantly surprised. I had cervical surgery recently and have had challenges sleeping on regular beds. I have not had any of the pain or issues I had before. Love the bed

Me and my baby love this mattress

Trying to get a good night rest while being pregnant seems impossible. Was surprised the 1st night sleeping on this amazing mattress that I had woken up after sleeping all night. We purchased this mattress to replace a Sleep Number bed which leaked air, leaving us sleeping at an angle by morning. So far, we've been very pleased with the bed. It was very easy to set up and is about 11" tall. It's a bit stiff which I understand typically goes away with time but it hasn't been a problem.

I'm skeptical

It is better than I thought it would be. Not too sure yet but I will keep sleeping on it and let everyone know how it goes. It seems like a pretty good bed so far.

Your Black Diamond Mattress Questions, Answered.

Each type offers a unique balance of comfort and support:

  • Quilted Hybrid: Features a plush euro top with a firmer core, ideal for side sleepers or anyone who prefers a soft, cushioned feel with gentle support.
  • Hybrid: Combines responsive coils and foam layers for balanced support and airflow, making it cooler and more buoyant. Great for couples or mixed sleepers.
  • All-Foam: Provides deep, contouring “hug” and targeted pressure relief, perfect for side sleepers or those with joint pain who want minimal motion transfer.

IceFlex Cooling Bands use advanced mineral technology to regulate body temperature—keeping you cool for 12+ hours. Flexible, sustainable, and adaptive, they contour to your shape for all-night cooling comfort and support.

No — our mattresses are 100% fiberglass-free.

Your health and safety come first. Every mattress is crafted using clean, sustainable, and non-toxic materials.

All foams are CertiPUR-US® certified, ensuring they’re made without ozone depleters, mercury, lead, or heavy metals, and have low VOC emissions for better indoor air quality.

They’re also GREENGUARD Gold certified, meeting strict standards for a healthier, safer sleep environment.

You can use any sturdy base that suits your space—box spring, platform, slatted, or adjustable.

Just make sure it has a solid top or slats spaced no more than 4 inches apart for proper support. A strong, even surface helps prevent sagging and extends your mattress’s lifespan.

If your mattress isn’t delivered with White Glove Service, setup is simple:

Open the box, remove the rolled mattress, and carefully cut the outer wrapping to let it expand.

For best results, allow 24–72 hours for full expansion. Avoid leaving your mattress boxed for more than 4 months to protect its structure and warranty. We recommend having two adults handle setup and unboxing to prevent strain or damage

The Black Diamond combines IceFlex Cooling Technology and CoolTouch fabrics for advanced temperature regulation and luxury support.

Yes — all Bamboo Is Better mattresses are compatible with any frame, including adjustable bases.

You have a 120-night trial to make sure it’s the right fit. If not, we’ll make returns simple and hassle-free.

Every mattress is handcrafted in the USA using non-toxic, CertiPUR-US® certified materials.

It’s normal for your body to need a few nights to adjust to a new mattress. Most sleepers feel fully comfortable within 2–3 weeks as their body aligns with the new support and pressure relief. Giving yourself that time helps ensure your mattress performs at its best.

Your mattress is backed by a 20-year limited warranty that protects against defects in materials or workmanship—such as sagging, foam breakdown, or spring issues—when used on a proper foundation. We stand behind every product to ensure lasting comfort and support.
