Nectar Classic 12” Memory Foam Mattress – Medium-Firm
Whether you need to replace your mattress alone or need a completely new setup with refreshed accessories, our sleep experts can guide you through the entire process and help you build the bed of your dreams.
The Nectar Classic 12” Memory Foam Mattress delivers a balanced combination of cooling performance, contouring pressure relief, and reliable long-term support. Designed with a medium-firm feel and five precision-engineered layers, this model is built to help sleepers achieve refreshing, restorative rest every night. Its breathable cooling cover, therapeutic memory foam system, and stable support foams work together to minimize motion transfer, promote alignment, and maintain consistent comfort throughout the night.
Comfort / Firmness
This mattress offers a medium-firm comfort profile, making it a strong choice for sleepers who want a stable, supportive feel without sacrificing contouring pressure relief. The memory foam layers cradle the shoulders, back, and hips while maintaining a firm overall structure that supports healthy alignment. For individuals who prefer a firmer surface or experience back discomfort, the Nectar Classic provides a dependable and uplifting sleep experience.

Construction Details
The Nectar Classic 12” features five thoughtfully engineered layers designed for comfort, cooling, and durability:
-
Cooling Quilted Poly-Blend Cover—cool-to-the-touch material that helps regulate temperature from the moment you lie down.
-
Therapeutic Memory Foam—conforms to the body’s natural curves for targeted pressure relief.
-
Comfort Support Foam—adds transitional support and enhances weight distribution.
-
Endurance Support Foam—a stable, long-lasting base layer engineered for structural integrity.
-
Shift-Resistant Lower Comfort Cover—keeps the mattress layers aligned and prevents unwanted movement.
All foams are CertiPUR-US® certified and the mattress is 100% fiberglass-free, ensuring safety and material quality.
Medical / Wellness Benefits
The Nectar Classic is designed to promote better spinal alignment and reduce pressure buildup in sensitive areas like the lower back and hips. The contouring memory foam supports natural posture, which may help alleviate stiffness and tension. Its cooling cover assists in preventing heat retention, contributing to fewer sleep interruptions. For sleepers seeking consistent support, reduced motion transfer, and improved nightly recovery, this mattress provides dependable wellness-oriented performance.

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.
