Experience the Diamond Mattress Snowbird Hybrid Firm at The Mattress Clinic in Oklahoma City, OK — a supportive, lifted hybrid mattress designed for sleepers who prefer a firm, stable, and highly structured feel. In our showroom, you can compare firmness levels side-by-side, and if you’d like additional clarity, optional insight from APRN-CNP Quynh Boerner is available to help you understand how different mattress constructions may support your preferred sleep posture — always optional, never clinical.

Key Features & Construction

The Snowbird Hybrid Firm is built on Diamond Mattress’s upgraded 15" hybrid platform, engineered with advanced cooling materials, titanium-infused foams, and a taller support system for superior stability. This is the firmest version of the Snowbird collection and is designed for sleepers who want strong support without excessive sink.

Key features include:

• Firm comfort level for maximum support

• CoolTouch™ temperature-regulating fabric

• Ice Flex Cooling Bands for enhanced temperature control

• High-Density Titanium-Infused Memory Foam

• High-density CertiPUR-US® transitional support foams

• 9-Series Individually Wrapped Coil System (taller, more supportive)

• Foam-encased edge support

• Approx. 15" profile height

• Smooth-top design

• Adjustable-base compatible

• 20-year limited warranty

Cooling & Temperature Control

Even with its firm support level, the Snowbird Hybrid Firm features Diamond’s advanced cooling system designed to help hot sleepers maintain a comfortable surface throughout the night:

• CoolTouch™ breathable, moisture-wicking cooling fabric

• Ice Flex Cooling Bands engineered to pull heat away from the body

• Titanium-infused memory foam to assist with heat dispersion

• Ventilated airflow created by the 9-Series wrapped coil system

These layers work together to create a cool, firm sleep environment ideal for warm sleepers who don’t want a soft mattress.

Support System & Durability

Diamond’s 9-Series coil system enhances durability, stability, and long-term performance. This reinforced support core provides:

• Strong, lifted support for the entire body

• High stability with very limited sink

• Better alignment for back and stomach sleepers

• Improved long-term comfort compared to lower-profile coil units

• Enhanced perimeter performance through foam-encased edges

The Snowbird Hybrid Firm is ideal for sleepers who want a mattress that stays supportive night after night.

Motion Cancellation Performance — Enhanced

The Snowbird Hybrid Firm earns an Enhanced motion cancellation rating due to:

• Individually wrapped coils that isolate movement

• High-density titanium-infused memory foam that minimizes surface vibration

Excellent for couples who want firm support without disruptive motion transfer.

Pressure Relief

Although firm, this model includes a thin layer of titanium-infused memory foam that provides light contouring for:

• Lower back

• Hips

• Shoulders

The surface feels stable and lifting, but still offers enough cushioning to prevent pressure accumulation.

Spinal Alignment

The Snowbird Hybrid Firm promotes healthy spinal alignment by:

• Keeping the midsection elevated

• Preventing excessive sink at the hips and shoulders

• Maintaining a straight, supportive sleep posture

This makes it an excellent fit for stomach and back sleepers who need firmer, flatter support.

Adjustable Base Compatibility

The Snowbird Hybrid Firm easily flexes with adjustable bases, maintaining support and comfort in every position.

Who This Mattress Is Best For

• Back sleepers

• Stomach sleepers

• Sleepers who prefer a firm, supportive feel

• Couples needing Enhanced motion isolation

• Hot sleepers wanting cooling features

• Adjustable-base users

• Oklahoma City shoppers seeking a lifted, durable hybrid

365 Night Sleep Great or Exchange Guarantee

Return Policy 

365 Night Sleep Great or Exchange Guarantee

A new mattress is like a new pair of shoes—it takes time for the new materials and your body to adjust to each other. And with the wrong socks (bedding), you could end up hating the correct shoes for you. Typically, it takes about 35–40 days for a mattress to start performing at its best if you use the proper bedding. After this “break-in period,” if you feel a different mattress style might work better, you may exchange your mattress up to 365 days from the purchase date. Using our bedding products with our mattresses ensures that the bedding isn’t causing any issues and that it is, in fact, the mattress that’s the problem. This is why you need a protector & pillow from us to receive the Exchange Guarantee.

These policies constitute the “365 Night Sleep Great or Exchange Guarantee” 
A $199 or 10% Exchange Fee (whichever is greater) applies to all reselections. This fee covers delivery for swapping the mattresses up to 20 miles from the store. The Mattress Clinic will allow a one-time re-selection ONLY after the 35-day adjustment or “break-in” period (Tempur-Latex 40-days). You have 365 days from the purchased date to exchange your mattress. You may select a mattress of equal or greater value of the same size. If you select a sleep surface of greater value, you will be responsible for the difference in price. If a reselection is of lesser value, no refund will be given. The original mattress purchase must include a mattress protector and pillow purchased before the mattress is received. The mattress surrendered must be stain free and odor free. We are unable to exchange stained, unsanitary, odor damaged (smoke/pets etc.), or damaged (ripped, burns, etc) mattresses under the Exchange Guarantee. Products must have been used only for their intended purpose. This includes using the product on an appropriate base, frame, or foundation.

Please take your time in your reselection choice; only ONE comfort exchange is allowed per customer. keep all receipts and original tags on your mattress. The Exchange Guarantee will be voided if you remove the original tag from the mattress or lose your proof of purchase. 
 
Reselections are not allowed for issues regarding mattress size or height. Bedding accessories such as pillows, protectors, sheets, adjustable bases, bedding foundation or furniture, are not eligible for exchanges. Reselections are not valid on “special sizes” (California King, split Queen, Etc.), custom orders, clearance merchandise, floor models or warranty exchanges. Your mattress reselection will be sold at “normal” sale price. Any discounts/gifts given with your original purchase of mattress, sheet set(s), mattress protector(s), pillow, and/or non-purchased gift cards will be added to the exchange fee. This means if you receive a discount/gift with your mattress and/or qualifying items and want to exchange it for the same mattress but a different feel, you are to pay the difference of the discount(s)/gift given, the exchange fee, plus any price increases made since your purchase (if increased). Your re-selection must be the same size as your original mattress purchase, Example: Queen for Queen.
