Duo Comfort

The DUO Memory Mattress consists of two main components: the DUO Core and the DUO Comfort. You choose between two Memory Foam DUO Comfort options that combine with the flippable DUO Core. Mattress shopping has never been simpler.

At the heart of the DUO Mattress is CLING™ - our patent-pending attachment method that takes the two DUO layers and makes them feel like one.

The DUO Core is our flippable mattress support that uses CLING™, our patent-pending attachment methodto attach your Memory or Memory Plus DUO Comfort layer to either side - giving you a firmer and a softer option all in one mattress.

Contour feel

The DUO Memory delivers comfort through memory foam, which provides pressure alleviation & low motion transfer.

The DUO Memory is a perfect solution for those looking for a contouring mattress that provides comfort to your hips and shoulders. Our goal is to provide undisturbed sleep throughout the night.

The Legacy Pocketed Coils offer unmatched support even for plus size sleepers. It also offers enhanced motion isolation to reduce partner disturbance.

We know you sit on your bed sometimes, so we designed the DUO Core with enhanced Edge Support. It is some of the best edge support you will find.



We use a high-density "AdaptFoam" on one side of the DUO Core to create a slightly softer side. "Flip" the DUO Core (our Logo will be upside down) and achieve a slightly firmer feel.

The DUO Core has high-strength handles in order for you to easily flip the support layer to achieve a different feel.


Discover a new era in mattress technology with CLING™, the groundbreaking innovation that bridges the gap between the DUO Core and DUO Comfort layers, transforming your DUO Mattress into a seamless sleep experience like no other.

Organic Cotton Knit fabric that is soft and breathable for a great night of sleep.


We use premium materials in order to provide a cool, clean & breathable feel on the surface.



"By far the best mattress I've ever owned or slept on. Love the hybrid technology, the excellent blend between comfort and quality. Also had an incredible experience with the staff from Engineered Sleep. Love this company and their product!!"

Brad T.

"The actual best mattress I’ve ever slept on! The quality is amazing. Will only buy from engineered sleep from now on!"

Hillary C.

"Absolutely fantastic. It's so comfortable. I had a much more expensive Casper beforehand. This mattress cost less, and it’s much more comfortable. The quality of this mattress is another level, craftsmanship is exceptional."

We crafted the DUO in a way that rewards you as a consumer. The DUO allows you to simply "refresh" your comfort as needed over the lifespan of the mattress.


We know that buying a mattress online can be scary. We do our very best to match our customer’s needs with the correct mattress. We do not make "junk" products just to hit a price point. From the bottom of our line to the top, we use high-quality components and never compromise our standards. We are confident that the product we sell you will meet or exceed your expectations. In the event that this does not happen - we have created this 100-Night Sleep Trial.

Try any of our mattresses for 100 nights. You must keep your mattress for at least 45 nights. Studies show that it sometimes takes several weeks for your body to adjust to a new mattress. If after 45 nights, but before 100 nights you are still unsatisfied you can then return your mattress for a full refund.

To receive your refund you must provide photo evidence of your mattress being donated. In certain cases we will have your mattress picked up and returned to us - this is at Engineered Sleep's discretion.

This applies to custom sizes, but not to custom mattress builds outside of our standard offerings.

If you are not satisfied with your purchase please email hello@engineeredsleep.com or call 866-244-0898.

During the first 100 nights of sleeping on your DUO mattress, you can make ONE Comfort Exchange.

You must sleep on the mattress for at least 30 nights to allow your body to become adjusted, if necessary. Between day 30 and day 45, if a change needs to be made, you can execute your ONE Comfort Exchange.

We offer free shipping to the 48 contiguous states. Most shipments will arrive via FedEx Ground. Your order will ship freight (LTL) if it includes an ES Power Base or is a custom size that is too large for FedEx Ground.

FedEx Ground deliveries arrive in a box and the mattress is compressed and rolled in plastic. They are delivered to your front door or garage. Once the boxes are with FedEx we can not control any delays.

Freight (LTL) deliveries are shipped on a pallet and delivered to your home via curbside delivery. A delivery appointment is required and you will be contacted for this to be setup. The freight company is not responsible for bringing this to your door, in your garage, or in your house.

The DUO Memory has a 10 Year Warranty on the DUO Support and a 5 Year Warranty on the DUO Comfort. You can refresh your DUO Comfort layer at an amazing price anytime.

All mattresses, with exception to custom orders, can be cancelled prior to shipping. After shipping confirmation and within the 100 Night Sleep Trial you can return your mattress for a full refund on the cost of the mattress. All mattress cancellations after the 100 Night Sleep Trial are non-refundable. Special orders are non-cancellable / non-refundable.
