Picking the right loft (height) comes down to fit and comfort. A few quick checks can help:

• Sleep position: Side sleepers often prefer a medium-to-high loft to keep the neck aligned; back sleepers may like something lower.
• Shoulder breadth: Broader shoulders usually benefit from a taller pillow. A simple approach is to measure from the base of your neck to the tip of your shoulder and look for a loft in that range, then factor in your mattress’s sink-in.
• Adjustability: Some designs include removable layers or inserts for fine-tuning.
• Dimensions: Compare listed measurements to your current pillow to gauge size.

Comfort is personal, so it may take a little trial and error. Checking reviews and product photos on Walmart.com can provide helpful real-world context.

They’re built for different goals, so your choice depends on how you sleep.

• Arm tunnel pillows: Feature an arch or channel so you can slide your forearm through without compressing the shoulder. Many side sleepers like them to reduce arm pressure or for cuddling positions.
• Cervical contour pillows: Use a curved profile to support the natural neck curve. They can suit side and back sleeping by helping maintain a neutral alignment.

Some options also include cooling covers or dual heights for versatility. Preferences vary, so consider your primary position and whether you need an arm passage or targeted neck contouring. If you’re shopping for recovery needs, it’s a good idea to ask your healthcare professional which shape is appropriate.

Most memory foam cores aren’t machine washable, but care is straightforward:

1. Remove the cover: Wash the removable cover on gentle with mild detergent; air-dry or tumble low if the label allows.
2. Spot-clean the foam: Mix a small amount of mild soap with water. Dab stains with a cloth—avoid soaking the foam.
3. Deodorize: Lightly sprinkle baking soda, let sit, then gently vacuum with an upholstery attachment.
4. Dry thoroughly: Air-dry the foam flat in a well-ventilated area; keep away from direct heat or sunlight.
5. Protect: Use a breathable pillow protector to reduce future stains.

Always follow the product’s care label. Cleaning methods can vary by material and construction, and gentle handling helps maintain the foam’s feel over time.

A few setup tweaks can make a noticeable difference:

• Align first: Keep your neck neutral (ear over shoulder) before threading your forearm through the tunnel.
• Adjust orientation: Rotate the pillow so the tunnel lines up with your preferred arm position; some designs can flip for different heights.
• Pair with support: A small knee or body pillow can help keep hips and shoulders aligned, which may feel more balanced.
• Let it expand: If vacuum-packed, allow 24–48 hours to fully loft and air out.
• Stay cool: Use a breathable cover and lightweight bedding if you sleep warm.

Comfort preferences vary. If discomfort persists or you’re recovering from an injury, consider checking with a healthcare professional for personalized guidance.
