I Tried the Core Products FOM170 for Side Sleeping in 2026: Real Experience and Drawbacks
Last updated: October 19, 2026 8:00:00 AM
Finding the right support for side sleeping can be a frustrating cycle of trial and error. The Core Products FOM170, also known as the Double Core Select, is an ergonomic cervical pillow designed to address these alignment challenges. Unlike static foam pillows, this model uses a system of interchangeable inserts to allow for a more personalized sleep surface.
1. Quick Answer
- What it is: A contoured foam cervical pillow featuring four interchangeable color-coded core inserts of varying firmness.
- Who it may suit: Back and side sleepers who need consistent neck support and prefer a customizable, firm foam feel.
- Key limitation: The precision-cut polyurethane foam does not have the “squish” of traditional down or shredded memory foam, which may feel too rigid for those accustomed to plush pillows.
2. What Is the Core Products FOM170 Double Core Cervical Pillow?
The Core Products FOM170 double core cervical pillow side sleep solution is a precision-cut orthopedic tool. It belongs to the category of ergonomic contour pillows, specifically designed to fill the gap between the head, neck, and mattress.
How it’s used:
The pillow features a “lobed” design. You place the higher side (the lobe) under your neck to maintain the natural curve of the spine. The “Double Core” name refers to its ability to house different support rolls—ranging from gentle to extra-firm—which you can swap out as your comfort needs change. While primarily marketed for back sleepers to restore cervical curvature, its 4-inch lobes provide the necessary height for many side sleepers to keep their neck neutral.
3. Key Features and Design
- Shape: A classic contour design with two different-sized lobes to accommodate varying neck lengths.
- Customizable Firmness: Includes four color-coded foam cores:
- White: Gentle support
- Blue: Medium support
- Black: Firm support
- Gold: Extra-firm support
- White: Gentle support
- Material: Constructed from high-quality, latex-free polyurethane foam.
- Cover: Comes with a breathable 50⁄50 cotton-polyester blend cover that is removable and washable.

5. Real-World User Feedback
Based on user experiences in 2026, feedback on the Core Products FOM170 double core cervical pillow side sleep performance is generally polarized:
- Positive: Many users appreciate the ability to “level up” the firmness. Those who have used Core Products for years often cite the durability of the foam compared to cheap retail alternatives.
- Neutral: There is a significant adjustment period. New users often report that it takes 3–7 nights to get used to the structured shape.
- Negative: Some find the foam to be “too hard,” even on the gentlest setting. Others have noted that the polyurethane foam can have a slight “new foam” smell (off-gassing) for the first 24 hours.
6. Limitations and Considerations
It is important to remember that this is a lifestyle comfort product, not a medical device.
- Not Universal: While it works for back and side sleepers, it is generally unsuitable for stomach sleepers due to the high profile of the lobes.
- Preference Driven: If you prefer the “sinking” feeling of memory foam, this precision-cut foam may feel too bouncy or stiff.
- No Guarantee: While it supports alignment, it does not gu Oct 18, 2026 · 2026 Winners · Best of Sarasota Explore the 2026 Best of Sarasota winners.

Yes, but the FOM170 uses a more resilient polyurethane foam rather than traditional “sink-in” memory foam.

The Core Products FOM170 double core cervical pillow side sleep experience is one of high-utility and customization.
