We want you to love sleeping on your Diamond Mattress as much as we loved hand-crafting it, which is why every purchase comes with a 120-night at-home sleep trial. This gives you plenty of time to experience the comfort and support of your new bed and decide if it’s the right fit for you. We recommend trying it for at least 30 nights to allow your body time to adjust. If you have a change of heart, no problem—returns or exchanges are free and easy within the 120-night window, starting from the day your mattress arrives.

The Diamond Flurry Lux stands out for staying cooler than most memory foam hybrids — thanks to its breathable layers, cooling fibers, and airflow-promoting coils.
The Diamond Flurry Lux mattress is a hybrid specifically designed for exceptional cooling performance. In fact, it’s one of the highest-scoring hybrids we’ve tested to date.
During our performance tests, this mattress had exceptional cooling, deep sinkage, extremely low motion transfer, extremely fast response time, moderate bounce, very good edge support, excellent sex performance, exceptional pressure relief, excellent off-gassing, and an exceptional company score as well. The Flurry Lux performed extraodinarily well across the board and is one of the best hybrid mattresses on the market.
"The Flurry Lux Cooling Hybrid is a well-crafted luxury mattress that won't break the bank. A Euro top cushioned with adaptive foam over sturdy pocketed coils creates a balanced, medium firm feel that many of our testers found both comfortable and sufficiently supportive."

The Diamond Mattress 120-Night Trial and Return Guarantee ensures you have plenty of time to decide if your mattress is right for you. If you’re not satisfied within 120 nights of delivery, we offer a hassle-free return or exchange, with no restocking or return shipping fees.
Just reach out to our customer service team via contact page or chat. You must give your mattress a fair trial of 30-60 days for proper adjustment. Returns are only valid for the original owner, purchases made directly from Diamond Mattress and must include the original law tag.
Returned mattresses are not resold but donated, and once confirmed, you’ll receive a full refund. Each customer is eligible for one return per household. Returns or exchanges due to wear, stains, or misuse (like improper foundation or mold) are not accepted.
No, Diamond mattresses are completely fiberglass-free. Our commitment to our customers' safety and comfort extends to every aspect of our production process, including our dedication to using clean, sustainable materials.
All our mattress foams are CertiPUR-US® certified, meaning they are made without harmful substances like ozone depleters, phthalates, mercury, lead, or other heavy metals and have low VOC emissions, ensuring a healthier sleep environment. Furthermore, our mattresses are GREENGUARD Gold certified, meeting the highest standards for healthy indoor air quality and promoting responsible manufacturing practices.
You can use any base that works for you, as long as it has a solid top or slats no more than 4 inches apart. A stable, supportive frame is essential to prevent sagging and ensure the longevity of your mattress.
Upon receiving your mattress, open the box, remove the rolled mattress, and carefully cut the outer wrapping to allow it to expand.
For optimal results, give it 24-72 hours to fully expand. To avoid damaging components and voiding the warranty, do not leave the mattress in the box for more than 4 months. We recommend that two adults handle the setup process, exercising caution while lifting, positioning, and unwrapping the mattress.
