The GhostBed Dimensions® Hybrid Mattress

Targeted comfort, support and cooling in our most luxurious mattress to date

Fall Asleep in Cool, Cozy Comfort—No Counting Sheep Required

Tired of waking up drenched in sweat? Yeah, us too. So we set out to create a mattress that actually works with your body to keep you cool, all night long. The GhostBed Dimensions with 3D Matrix® Hybrid is the ultimate sleep upgrade, featuring 7 layers of comfort including our patented gel polymer—our secret sauce for cool, restorative sleep.

How Does The GhostBed Dimensions with 3D Matrix® Feel?

Imagine a soft yet supportive mattress, with seven layers of comfort all designed to stretch, contour and cradle your body. Beautifully balanced firmness for all sleeper types, it’s the art and science of the perfect mattress.

GhostBed Comfort Scale - 4 – 5 COMFORT

The GhostBed Dimensions with 3D Matrix® is slightly softer than the original GhostBed, thanks to the stretchy gel polymer layer, contouring Ghost Bounce layer and super-soft transition foam.

Plush feel
7 layers of comfort technology designed to adjust to your individual body shape

Soft transition foam contours your body, relieving pressure from head to toe
High-density foam core encourages good spinal alignment, without feeling too firm

Buh-Bye Excess Heat, Hello Amazing Sleep

Did you know that as you fall asleep, your body naturally tries to lower its core temperature? With GhostBed Dimensions patented 3D Matrix technology, now your mattress can work with you so you fall asleep faster and stay asleep longer. No more tossing and turning, just comfortable sleep so you can wake up to an amazing morning. (Alarm clock and coffee not included!)

7 Layers of Hybrid Comfort & Our Patented 3D Matrix Technology

1. Ghost Ice Cooling Cover — Instantly cool to the touch, our deliciously plush cooling fabric is soft, supple and gently soothing.
2. 3D Matrix Polymer Layer — The patented gel polymer layer attracts excess body heat, driving it away from your body instead of leaving it trapped within the mattress.
3. 2" of Gel Memory Foam — Naturally-cooling gel memory foam contours to your unique body shape, stretching in all directions to continuously relieve pressure.
4. 4. Ghost Bounce Layer — Exclusively ours—responsive like latex, contouring like memory foam. The Ghost Bounce layer is as close as you can come to floating without leaving the ground.
5. Ghost 3D Matrix Soft Transition Foam — The soft transition foam provides additional pressure relief, distributing your weight and reducing the need to toss and turn.
6. Individually Wrapped & Reinforced Coils — Individual coils offer the responsive support of traditional innerspring mattresses, without the worry of wearing out after just a few months. We’ve also reinforced the coils around the perimeter with our proprietary Spirited Edge™ support, making it easier to sit comfortably on the edge without slipping off.
7. High-Density Support Layer — A solid inch of foam underneath the coil layer provides extra support and durability.

How It Works

Forget the science-y mumbo-jumbo... what does the 3D Matrix polymer layer actually do?

See that honeycomb-shaped pattern? We’ve filled the gaps with gel polymer, which instantly reacts to your body weight. As the gel absorbs excess heat, the unique shape of this layer helps it draw heat away from you—instead of trapping it within the mattress, like many others do.
Additional foam layers work alongside the 3D Matrix layer, stretching in all directions and relieving pressure points to virtually eliminate tossing and turning. Translation? You stay asleep longer, and wake up feeling totally refreshed.
Bonus: our gel technology is soy-based and eco-friendly, so you can feel good about what you’re sleeping on.

 

Spirited Edge^™ Support

For superior sleeping AND sitting

With our Spirited Edge^™ support design, you won’t have to worry about this all-too-common issue. Individual 6" coils create the weightless feeling you love, while wrapping them individually creates minimal motion transfer.

Plus, two rows of specially reinforced coils along the edge of the bed make it easy to sit comfortably without slipping off.

Great Sleep

"This mattress has been a life changer for us! We were looking for something that felt a lot like Tempur material and got that from the 3D Matrix. Very heavy and difficult to get into our bedroom but was ready to be slept on that same night. Became more firm by day two but perfectly "molded" by one month of ownership. I cannot feel my partner moving on their side which is a plus with weird sleep schedules. Came with video directions for unpacking."

– GhostBed Owner – Theresa C., 5-star review

Science is on our side, so you'll sleep well on all sides

With more than two decades of expertise under our belt, we know mattresses. Now we’re proud to introduce our most luxurious, cooling mattress to date.

The first of its kind, the 3D Matrix features comfort layer technology that reacts and adjusts to different body shapes and temperatures at the same time, so you and your partner get the ideal sleeping environment. The gel polymer layer stretches in every direction to distribute your weight evenly, while absorbing excess heat throughout the night.

(P.S. It’s got 2 patents, too—you won’t find this kind of cutting-edge technology on any other mattress out there!)

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.
