Our original reviewer liked the iSense Smart Pillow’s soft cover, responsive foam and two adjustable fill compartments. The removable sensor added sleep-tracking features, but the original review did not validate their accuracy. Current product availability and app support have not been confirmed.
What our reviewer found
The reviewer liked the silky-soft cover, stitching and perimeter band, which gave the pillow a more structured shape. The fill rebounded quickly in the original test, and the two separate compartments made it possible to adjust the top and bottom portions individually. The reviewer also appreciated being able to remove the electronics.
Those are observations of the original sample. They do not establish the pillow’s long-term durability or the performance of a current product.
How the original pillow worked
The tested pillow combined adjustable foam with a removable sensor and tracker. The original article described a Bluetooth connection to a companion app and removable electronics for laundering. Check the label and manufacturer instructions for your own product before washing; do not put electronic parts in the wash.
The historical listing described queen and king sizes. Check actual dimensions, fill and care instructions if considering remaining stock or a used product.
What a sleep tracker can—and cannot—tell you
The original device was marketed to estimate sleep timing, movement and other measures. Consumer sleep estimates are not the same as a clinical sleep study, and this review did not compare the sensor’s readings with laboratory measurements. Do not use the device to diagnose sleep apnea or another medical condition.
For any older connected device, check whether the app still exists, supports your phone and can pair with the hardware. Confirm privacy settings, charging parts and return terms before buying.

Who might consider a similar pillow?
Useful for experimenting with height, even if you do not need electronic tracking.
May interest people who enjoy estimates and trends, provided the app and device still work together.
