The iSense Select is like no other mattress. From 3-zoned support, to multiple built-in cooling elements, to non-tech adjustable firmness, iSense Select is a step above the rest. 

Each iSense Select features the following support layers: 

• Cooling Next-Gen Response Foam — The most reliable, durable and breathable foam on the market creates ideal temperature-balancing comfort. Open-cell, Certi-PUR-US® Certified foam just below the cooling cover contours to your body to provide pressure relief and comfort. 
• Lightweight and Breathable Cover — The cool-touch cover is removable and sewn with cool-to-the-touch thread to add additional cooling properties. 
• Active response transition layer—This high-resilience, Certi-PUR-US® layer creates three-zoned lumbar support in the center-third from the shoulders to hip area. It offers fast-response support to maintain alignment for rejuvenating sleep. 
• Hundreds of Precision-Crafted Coils — Every mattress features hundreds of individually-wrapped pocket coils to evenly distribute weight throughout the mattress and ensure the best motion isolation. You can adjust the firmness of your mattress by replacing these coils with either more plush or firm coils in minutes. 
• Perimeter and edge support. Extra firm foam surrounds the perimeter of the pocket coil system. Reinforced edges provide stable edge seating and make it easier to get out of bed. 
• Modular, Adjustable Design—Every mattress features Medium pocket coils, but also comes with extra Plush and Firm pocket coil sets. You can easily swap coils from one or both sides of the bed to adjust to your perfect level of firmness. 

The iSense Select is perfect for those looking for an affordable, dual-comfort mattress alternative. The iSense Select offers adjustable firmness on each side of the bed without the use of any devices. 

In addition, with layers of motion-reducing foam and individually-pocketed coils, motion transfer is at a minimum and you rest comfortably and undisturbed. All of our beds have a responsive top foam layer that contours to your body for a more comfortable, deeper sleep.The iSense Select has an additional element of three-zoned, center-third lumbar support. iSense Select foam has 2X more airflow compared to other foams on the market. 

Each iSense Select mattress comes fitted with two Medium pocket coil sets, one for each side of the bed. It will also come with Plush and Firm replacement pocket coil sets so you can adjust the firmness of your mattress, if desired. You simply unzip the mattress cover, lift out the out pocket coil set and replace them with a new firmness on one or both sides of the bed. Adjust your mattress in minutes!

Yes, every iSense Select mattress is adjustable but not in the same way as the other iSense mattresses. The iSense Hybrid Premier and the iSense Classic both feature Comfort Control™ technology that adjusts the firmness of the bed using a pump & remote to switch between twenty different comfort settings at the touch of a button. 

The iSense Select is different in that it does not include any devices at all. It is a non-tech adjustable mattress with the option to adjust your firmness by hand. Each mattress features replaceable pocket coils and extra pocket coil sets you can use to swap out your firmness for a more plush or firm option on one or both sides. The variance in firmness between pocket coil sets is what determines the firmness of each side of the mattress.

1- Unzip the outer cover of your mattress. Don’t worry: It is easy to re-zip when you are done. 

2- Lift the cover to reveal the pocket coils you’d like to replace underneath. When you lift the top part of the mattress, you will see the labeled pocket coils underneath. 

3- Remove the current pocket coils from one or both sides of the bed. Lift up from the middle and then ease out the sides. 

4- Cut open the plastic of your replacement coils with care. Be cautious of cutting through the pocket coils themselves. 

5- Allow coils to decompress for a minute or so. The coils should unroll seamlessly and begin to decompress on their own. 

6- Move your new pocket coil set into place on one side of the bed. Start by setting the middle into place and then push down on the edges. It should be a perfect fit. It doesn’t matter which end is near the head or foot. 

7- Zip up the outer mattress cover. Fold the top part of the mattress back over so it lays flat. Zip together both parts of the mattress so it is secure. 

8- Your bed is now more firm or plush than before. It may take a few nights for your body to adjust to the new firmness feel. Enjoy better, deeper sleep! 

Congratulations, you adjusted the firmness of your mattress in just a few minutes!

The iSense Select is offered in Twin XL, Full, Queen, King, King FlexHead, King Split, and California King.

The iSense Select mattress is a hybrid, meaning that it is equipped with both foam and pocket coils to provide the optimal level of comfort and support. It is different from the other iSense mattresses because the Select allows for adjustability without smart technology or devices.

Unlike other hybrids on the market, you can customize or adjust the firmness on each side of the mattress by hand to provide one of three levels of comfort: plush, medium or firm. The bed’s firmness is defined by the firmness level of the pocket coil layer. Every mattress will come with medium pocket coils in the mattress, but it will also come with additional replacement sets of plush and firm coils. You can then use these coils to adjust the firmness of your mattress at any time. 

To change the coils within your mattress, you simply unzip the mattress cover, replace the pocket coils, and rezip the cover. It just takes minutes!

We choose to sell our mattresses directly to consumers online because we believe in-person shopping at a retail store is not the best way to buy a mattress.

Why’s that?

Simple: Choosing a mattress while wide awake at a mattress store is very different from actually sleeping on one. And it’s only when you sleep on a mattress for an extended time that you will know whether or not it is a good fit.

Studies prove consumers are only 38% likely to select the right mattress in a store environment–and even more, shoppers usually choose the opposite mattress of what they truly need.

That’s why it is our goal to produce a bed that can work for everyone. Our iSense Select is essentially 6 mattresses in one (three firmness options on two sides of the bed), and we offer our 180-night risk-free trial. If after 45 days, you don’t love your bed, we will pick it up and refund your money. No hassle.

No, the iSense Select does not contain any smart bed technology, remotes or devices of any kind. It is adjustable through hand-replaceable pocket coils on each side of the bed. 

If you are looking for a smart bed, the iSense Hybrid Premier or the iSense Classic would be great options.

All new mattresses and owners require time to adjust to a new level of comfort, so we offer a 180-night risk-free trial period. During the first 180 days, try out the different firmness options included in your delivery by swapping out the built-in medium coils with the extra plush or firm coils. It takes a few days for you to adjust to each new level of comfort. 

Your comfort is our priority and we want to make sure your mattress offers the support you need. After 45 nights and before 180 nights, if you decide you don’t like your mattress, let us know. We will arrange the return.
