A pillow with adjustable fill or layers can make it easier to find that height, while a firmer, fuller pillow may suit you if you prefer steady support.

Our Picks: Best Best Pillow For Side Sleepers reviews
1. Nuzzle Adjustable Neck Pillow: Best for Customizing Loft
The Nuzzle pillow uses removable layers to change its height and feel. The brand describes it as a three-in-one design: use the slim layer for a softer, lower pillow, the medium layer for a medium-firm setup, or both layers for a firmer, higher feel. For side sleepers, the two-layer setup is intended to fill the gap between the shoulder and head.
Its Nanocoil fiber fill and PCM fabric cover set it apart from the foam options in this guide. The fabric is designed to absorb, store, and release heat, though how cool it feels can depend on your room and personal preference. The standard size measures 16 by 24 inches, so it may feel compact if you are used to a queen-size pillow.
The main advantage is the ability to fine-tune the loft without adding loose fill. That can be useful if you are unsure how high your pillow should be or switch between side and back sleeping. Expect to spend a few nights adjusting the layers to find a comfortable setup rather than assuming the first configuration will be right.
Pros:
- Three layer combinations let you adjust height and firmness.
- The brand recommends both layers for side sleeping.
- PCM fabric is designed to help manage heat.
- Fiber fill offers an alternative to memory foam and feather fill.
Cons:
- The standard size is smaller than a queen pillow.
- Finding the preferred loft may take some trial and adjustment.
Verdict: Choose the Nuzzle if adjustable layers are more important to you than a larger pillow size or a one-step setup.
2. Beckham Hotel Collection Pillow Set: Best Medium-Firm Pair
This set includes two queen pillows filled with hollow-fiber down alternative. Each measures 20 by 28 inches and has a cotton cover. The listed feel is medium-firm, which may appeal to side sleepers who want a pillow that holds its shape rather than compressing easily under the head.
The cotton cover is certified to OEKO-TEX STANDARD 100, and the fill is feather-free. The product description says the pillows can be washed on a gentle cycle and air-dried. After unpacking, the brand recommends shaking them and giving them time to reach their full loft.
Unlike the Nuzzle and QUTOOL, this pair does not offer a way to adjust the fill or layers. That makes it simpler to use, but less customizable if the height does not suit your shoulder width or mattress. The product description also highlights an 8-inch loft; since perceived height can vary with how a pillow compresses, consider whether you generally prefer a fuller pillow before choosing it.
Pros:
- Two queen-size pillows are included.
- Medium-firm feel is intended to provide steady support for side and back sleepers.
- Cotton cover is breathable and OEKO-TEX STANDARD 100 certified.
- Feather-free fill and machine-washable care make upkeep straightforward.
Cons:
- The fill is not adjustable.
- The fuller loft may not suit sleepers who prefer a lower pillow.
Verdict: This pair is a practical choice if you want two medium-firm, queen-size pillows and do not need adjustable fill.
3. Sasttie Firm Pillow Set: Best for Plush, Full Support
The Sasttie set includes two queen-size pillows with down-alternative fill. The filling blends 3D and 7D fibers, which the brand describes as balancing softness with a plump, firm feel. For side sleepers, that fuller profile may help keep the head from sinking too far into the pillow, though the right height depends on your build and sleep surface.
These pillows have an embossed geometric pattern and satin piping for a more finished look. Their cover is OEKO-TEX STANDARD 100 certified, and the pillows are machine washable. The brand suggests cold water and low-heat tumble drying, and recommends a low-heat dryer cycle after unpacking to restore the fill’s plushness.
There is no stated loft-adjustment feature, so you cannot remove fill if the pillow feels too high or firm. Compared with the Beckham pair, Sasttie emphasizes a plump, huggable feel rather than a specifically described medium-firm feel. It may suit you if you like a fuller pillow, but could be less appealing if you want a flatter, softer surface.
Pros:
- Two queen-size pillows are included.
- Plush fiber fill is designed to stay full and supportive.
- OEKO-TEX STANDARD 100 certified.
- Machine washable for easier care.
Cons:
- Fill cannot be removed to adjust the loft.
- The firm, full feel may not suit those who prefer a soft or low pillow.
Verdict: Consider Sasttie if you want a pair of full, firm-feeling fiber pillows and are comfortable choosing a fixed loft.
4. Utopia Bedding Gusset Pillow Set: Best for a Structured Shape
These queen-size pillows use down-alternative fill and have gusseted edges with piping. The gusset gives the pillow a more structured shape, which may appeal if you want a defined edge rather than a pillow that looks uniformly flat. The cotton-blend cover is described as breathable.
The product is presented as suitable for side, back, and stomach sleepers, but the supplied details do not give a specific loft or firmness rating. That makes it harder to predict whether it will provide enough height for your shoulder space. If you know that you need a particular loft, an adjustable option may be easier to fine-tune.
Care is another point to consider: the listing describes spot cleaning rather than machine washing. That may be less convenient than the washable Beckham and Sasttie options. This set is best viewed as a simple, hotel-inspired pair with a shaped design, rather than a pillow built for precise height adjustment.
Pros:
- Gusseted edges create a structured shape.
- Two queen-size pillows are included.
- Cotton-blend cover is designed to promote airflow.
- Down-alternative fill suits shoppers avoiding feather fill.
Cons:
- The supplied details do not specify loft or firmness.
- Care instructions call for spot cleaning, not machine washing.
Verdict: Pick this set if you value a gusseted, hotel-style shape and are comfortable with spot-clean-only care.
5. QUTOOL Cooling Memory Foam Pillow Set: Best Adjustable Option for Hot Sleepers
QUTOOL’s queen-size set pairs shredded memory foam with adjustable fill. Zippered covers let you add or remove foam to change the pillow’s loft and firmness, which can help side sleepers tune the height to their preferred position. The shredded construction is also intended to allow airflow through the fill.
The cover has two sides: a cool-touch side and a softer side made from polyester and rayon derived from bamboo. The cooling surface is designed to feel cool to the touch, but fabric temperature can be affected by the room and bedding around it. The brand also suggests pairing the pillow with cooling bedding and an air-conditioned room for a cooler sleep environment.
The foam is described as CertiPUR-US certified. The brand recommends airing the pillows out for a day or two after unpacking. Compared with the Nuzzle, this set offers a different kind of adjustment: you remove or add loose foam rather than changing layers. That gives you more fine control, but handling the fill may take extra effort. The supplied details do not specify washing instructions, so check the care label before cleaning.
Pros:
- Removable shredded foam lets you adjust loft and firmness.
- Two queen-size pillows are included.
- Double-sided cover offers a cool-touch side and a softer side.
- Foam is described as CertiPUR-US certified.
Cons:
- Adjusting loose fill can be messier than changing a layered pillow.
- The cooling feel depends on the room and surrounding bedding.
Verdict: Choose QUTOOL if you want adjustable foam fill and a cool-touch cover, and do not mind taking time to set up the pillow.
How to Choose a Pillow for Side Sleeping
Match the Pillow Height to Your Shoulder Space
When you lie on your side, your pillow needs to fill the gap from your mattress to your head. A pillow that is too low can let your head dip toward the mattress, while one that is too high can push it upward. Your shoulder width, mattress feel, and preferred sleeping position all affect the height that feels comfortable. Adjustable pillows such as the Nuzzle and QUTOOL make it possible to change the loft if your first setup feels off.
Choose a Feel That Holds Its Shape
Side sleepers often prefer a pillow that does not compress too much under the weight of the head. A fuller or firmer pillow may feel more supportive, while a softer pillow can feel plusher but may sit lower. The Beckham and Sasttie options use down-alternative fiber, while QUTOOL uses shredded memory foam. If you are unsure, look for a design that lets you adjust the height rather than relying on a fixed fill level.
Decide Whether You Want Fiber or Foam
Down-alternative fiber pillows offer a familiar soft, fluffy feel and are featured in the Beckham, Sasttie, and Utopia Bedding sets. Shredded memory foam, as used in QUTOOL, offers adjustable fill and a different, more foam-based feel. The Nuzzle uses layered Nanocoil fiber. Think about whether you prefer a pillow you can fluff, one you can customize by removing fill, or one with removable layers.
Consider Temperature and Cover Fabric
If you tend to sleep warm, pay attention to the cover and construction. The Beckham pillow has a cotton cover, Utopia Bedding uses a cotton-blend cover, and QUTOOL includes a cool-touch side. Nuzzle’s PCM fabric is designed to manage heat. These features can affect how the pillow feels, but no cover can guarantee that you will stay cool in every room or sleep setup.
Check Size, Set Quantity, and Bed Fit
The Nuzzle in this guide is a standard-size pillow measuring 16 by 24 inches. Beckham is a queen-size pillow measuring 20 by 28 inches, while Sasttie, Utopia Bedding, and QUTOOL are sold as queen-size sets of two. Check your pillowcase size and whether you are shopping for one pillow or a matching pair before deciding.
Review Care Instructions Before Buying
Care requirements vary across these options. Beckham and Sasttie are described as machine washable, while Utopia Bedding calls for spot cleaning. The supplied details for QUTOOL do not specify cleaning instructions, and the Nuzzle description focuses on adjusting its layers rather than washing. Check the product label and care guidance before cleaning to help protect the pillow’s materials.
Frequently Asked Questions
What pillow loft is best for side sleepers?
The best loft is the one that fills the space between your shoulder and head while keeping your head from tilting noticeably up or down. The right height varies with your body, mattress, and comfort preference. Adjustable pillows can help you make small changes if a fixed loft does not feel right.
Are firm pillows better for side sleepers?
Not always. A firmer pillow may hold its height better, but comfort depends on your body and how much the pillow compresses. Side sleepers should look for enough support to keep their head level without creating uncomfortable pressure.
Is an adjustable pillow worth considering?
An adjustable pillow can be useful if you are still figuring out your preferred height or change positions during the night. The Nuzzle uses removable layers, while QUTOOL lets you add or remove shredded foam. Both require some setup to find a suitable feel.
Which pillow in this guide is designed with hot sleepers in mind?
QUTOOL has a cool-touch cover side, while Nuzzle uses PCM fabric intended to help manage heat. Beckham and Utopia Bedding also describe their covers as breathable. Your room temperature, bedding, and personal comfort can affect how cool a pillow feels.
Can I machine-wash these pillows?
Beckham and Sasttie are described as machine washable, with specific care directions provided in their product details. Utopia Bedding is listed for spot cleaning. For Nuzzle and QUTOOL, check the product label or current care instructions before washing.
Should I buy one pillow or a set of two?
A single pillow may be enough if you are replacing only your own pillow, while a pair can be convenient for a bed or guest room. In this selection, Nuzzle is a standard-size pillow, and the other listed options are sold in sets of two.
Final Recommendation
For side sleepers who want the most direct way to change pillow height, the Nuzzle Adjustable Neck Pillow is the standout because its removable layers create three configurations. If you prefer queen-size pillows, the Beckham set offers a medium-firm down-alternative feel, while QUTOOL is worth considering if you want adjustable shredded foam and a cool-touch cover. Choose based on the loft, material, care routine, and size that best match your needs.
