Read the full reviewCoop Original lets you change the amount of loose fill. Side Cube Original is a fixed 12 × 24 × 5-inch block. The meaningful choice is between a pillow you can retune and a preset shape that must already suit your side-sleeping setup.
This is a research comparison based on the linked manufacturer documentation. We have not measured comfort, overnight temperature, or durability in a side-by-side test.
Side by side
| Coop Home Goods Original | Pillow Cube Side Cube Original | |
|---|---|---|
| Construction | Memory foam and microfiber | Fixed memory-foam block |
| Height control | Add or remove loose fill | No; Original is fixed, Riser differs |
| Advertised height | Adjustable; advertised loft varies with fill | 5 inches; Original 12 × 24 inches |
| Evidence | Manufacturer documentation; no physical test | Manufacturer documentation; no physical test |
Adjustment is the deciding difference
Coop lists cross-cut memory foam and microfiber with additional fill included. Adjust gradually and keep the removed fill so you can reverse a change.
The Original Side Cube does not have a loose-fill adjustment system. Do not confuse this model with Pillow Cube’s separate adjustable Riser products.
Changing positions during the night
A height that supports your side position can be too tall when you turn onto your back. If you change positions often, consider how much the pillow can be reshaped and whether a fixed block works in both positions.
Five inches is the Original’s advertised height, not a measurement under your head. Mattress sink and compression affect the working height.
Care and buying risk
Coop lists the pillow and cover as washable; follow its exact washing and drying instructions. Verify the Side Cube care label separately rather than treating all foam pillows alike.
Compare the exact sizes in your cart and the seller’s opened-pillow return policy. A fit mismatch is more difficult to correct when height cannot be adjusted.
Before you choose either pillow
- Match the listed model, size, and height to the item in your cart. Similar names can refer to different products.
- Check the height while lying on your own mattress. Advertised loft is not a measurement under your head.
- Read pillow-specific return terms, including opened-product eligibility, fees, and the seller’s policy.
- Check cover and inner-fill care separately. Cooling materials do not establish all-night cooling.

Frequently asked questions
Is Side Cube Original adjustable?
The Original listing checked for this comparison is a fixed 5-inch design. Riser is a separate adjustable product; verify the model name before buying.
Which is better for combination sleepers?
Coop offers more ways to change fill height and shape. That flexibility may help when you change positions, but it does not guarantee comfort.
