iSense Select Mattress Review
An innovative hybrid with a modular design for adjustable firmness.
$1,699 from iSense (queen)
Price Range: $1,199 – $2,499
Mattress Type: Hybrid
Firmness Options: Medium Soft (4), Medium (5), Firm (7)
Pros & Cons:
In 2018, iSense launched its sleep product line focused on accommodating couples without compromise. The company currently produces bedding, bases, and mattresses. The iSense Select Mattress is a hybrid model with a modular design that allows sleepers to manually adjust the firmness by switching out the coil system.
This is a departure from the brand’s other models, the iSense Hybrid Premier Mattress and the iSense Classic Mattress, which both contain air chambers so that sleepers can change the feel via the company’s app. Because of its lower-tech design, the iSense Select Mattress comes at a more budget-friendly price-point. The air-based models offer a broader spectrum of firmness options, ranging from soft (3) to firm (7). However, the iSense Select Mattress includes three of the most popular firmness options: medium soft (4), medium (5), and firm (7).
We’ll break down how the iSense Select Mattress performed in our lab-based tests, including which firmness levels were most comfortable for different types of sleepers.

Testing Team Takeaways
To test the iSense Select Mattress, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.

The iSense Select was an interesting twist on a multi-firmness bed. I was especially happy to see a hybrid design here, since I love the feel of hybrids over airbeds. Overall, the bed performed like a great hybrid, but with the bonus that I could change out the coils if I wasn’t getting comfortable. I’m a back sleeper, but prefer my beds a little softer, so the medium (5) set of coils was my favorite.

I was fascinated at first by the design of the iSense Select, since you can swap out the coils to change the bed’s firmness. It’s pretty slick and relatively easy to do, and if you have a larger mattress size like a queen, you can swap out the coils on each side. As a combination sleeper, I found myself having fun swapping between the medium soft (4) and medium (5) coil sets depending on what I wanted that night.

Beds with split firmnesses like the iSense Select are great for couples, since everyone can choose the firmness they personally want to lay on. Airbeds are famous for their freedom of firmness choice, but they’re pretty pricey, so it’s good to see newer options like this. Personally, I found myself most comfortable on the firm (7) set of coils.
Sleeping Style and Body Weight
Side Sleepers
The iSense Select’s two polyfoam comfort layers cushion and cradle a side sleeper’s curves, while zoning in the second layer also promotes good posture. This combination provides notable pressure relief without sacrificing support.
Our testers gave all three of the iSense Select Mattress’ firmness options high marks for side sleeping. However, the plush (4) and medium (5) options were especially comfortable for testers under 230 pounds.
Back Sleepers
Back sleepers typically benefit from stable support, which the iSense Select can provide. This model’s two polyfoam comfort layers mold to a sleeper’s lower back to provide support. At the same time, the zoning bolsters their hips to prevent uncomfortable sagging and potential lumbar strain.
Members of our team generally preferred the iSense Select Mattress’ firm (7) option for back sleeping, though those under 230 pounds also found the plush (4) and medium (5) variations comfortable for this position.
Stomach Sleepers
Sag-free support is critical for a stomach sleeper’s posture, and the iSense Select Mattress fits the bill for many individuals. While the two polyfoam comfort layers prevent the surface from feeling hard against the front of a sleeper’s body, zoning in the second layer reduces the risk of the sleeper’s abdomen sinking in too deeply and pulling their spine out of alignment.
Because the right level of conforming and support is so critical for stomach sleepers, our testers’ firmness preferences corresponded directly to their weights. Team members under 130 pounds thought the plush (4) was a good match, while those over 130 pounds preferred the firm (7).
Mattress Performance
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.

iSense Select Mattress Review Breakdown
The iSense Select is a hybrid mattress that measures 12 inches thick, qualifying as a high-profile model. It uses a modular design to allow for three changeable firmness options: medium soft (4), medium (5), and firm (7). Note that iSense refers to its medium soft (4) option as plush.
A fabric cover designed for cooling wraps around the exterior of the mattress. The top layer of the comfort system consists of 2.5 inches of polyfoam. This material uses an open-cell structure intended to cool the mattress. At the same time, it conforms to the sleeper’s body to cushion it and ease pressure. A second 1.5-inch polyfoam comfort layer underneath incorporates distinct firmness zones, reinforcing the center third of the bed for increased lumbar support.
One of the iSense Select’s most unique features is its 6-inch pocketed coil core. Each mattress comes with interchangeable coil systems to adjust the firmness. The coil layer is accessible by unzipping the top portion of the mattress. Sleepers can then switch out the coil system for a different firmness option. Mattress sizes intended for two people have a separate coil system on each side of the bed, allowing partners to select separate firmness options. Since the coils are pocketed, they also limit motion transfer, add responsiveness, and enhance contouring.
A foam encasement wraps around the outside of the coil system to hold it in place while fortifying the edge to allow sleepers to sit and lay securely along the perimeter. A 2-inch layer of polyfoam under the coil system provides a firm base to support the coils as they compress.

Mattress Prices and Sizing
The iSense Select Mattress falls right around the average price for a hybrid model. Its versatile design adds to the value by allowing you to change the feel rather than purchasing a new mattress if your needs or preferences change. This feature is more common in higher-priced models.
The iSense Select Mattress comes in most of the standard mattress sizes except for standard twin. King sizes with a split head are also available, as is split king size.

Trial, Warranty, and Shipping Policies
The iSense Select Mattress ships within the United States. It is available exclusively through the official iSense website.
iSense ships for free within the 48 contiguous states. It usually takes 2 to 4 weeks for the mattress to arrive. The company also ships to Alaska and Hawaii for an additional fee. Shipping times may vary.
The standard shipping option involves self-installation. A local hub will contact you to schedule a to-your-door dropoff. From there, you’re responsible for bringing it in and setting it up. The mattress is compressed and rolled to make it more maneuverable. However, since larger mattress sizes can weigh up to 145 pounds, installation generally requires two adults.
Once you’ve moved the packaged mattress to your room of choice, unbox it, remove the plastic, unroll it, and let it expand for a few hours before use.
iSense offers White Glove delivery for an additional charge. The installers will bring the mattress into your home, set it up, and remove the packaging. Old mattress removal is not available at this time.
The iSense Select Mattress comes with a 180-night sleep trial. iSense requires that customers keep the mattress for at least 45 nights, making the mattress eligible for return after night 45 and before night 180. iSense will arrange to pick up your unwanted mattress and refund the full purchase price once the mattress passes inspection to ensure it remains undamaged.
A 25% restocking fee applies to any returns initiated before 45 days are up.
The iSense Select Mattress comes with a 10-year limited warranty. This policy protects against defects in materials and workmanship, including deterioration resulting in an indentation over .75 inches and flaws in the mattress cover that cause cracking or splitting. iSense will repair or replace mattresses with qualifying defects. Pickup, shipping, and delivery charges may apply.
The warranty does not apply to damage from abuse or misuse, and it may be voided if you fail to use a proper foundation.
