ZonLi Cooling Body Pillow for Adults, Long Pillow with Memory Foam Adjustable, Firm Support Body Pillow for Side Sleeper, Washable Pillowcase, 20x54 inch, Grey Review (2026)

Updated September 21, 2026 · Research-based review

Our verdict

A full-length body pillow for side sleepers who want firm, adjustable support from shoulder to knee rather than a soft hug pillow. The zippered fill lets you tune firmness and the cover is washable, but the firm feel and foam weight make it less suited to anyone who wants a plush, lightweight cuddle pillow.

Who this pillow fits

At 20 by 54 inches, this body pillow is long enough to run from shoulder to knee for a side sleeper, which is the main use case it is built around, including support for pregnancy and general back pain relief while lying on one side. Because the support is described as firm, it suits people who want a body pillow that holds its shape and pushes back rather than one that compresses easily under a leg or arm. Anyone who prefers a soft, squishy hug pillow may find the firm memory foam feel stiffer than expected, so this is a better match for someone prioritizing support over softness rather than a cuddle-style pillow for casual lounging.

Materials and construction

The fill is adjustable memory foam accessed through a zippered opening, so the firmness and loft can be tuned by adding or removing foam rather than being locked in at the factory setting. The outer layer is a washable pillowcase, letting the cover be removed and cleaned separately from the foam insert inside. At 20 by 54 inches, the pillow is sized to support the length of a side sleeper's body from shoulder to knee, which is a common body pillow dimension for that use case, rather than the shorter bolster-style pillows that only support a smaller section of the body.

How it handles heat

The listing markets this as a cooling body pillow, which for a memory foam fill pillow typically comes down to the fabric of the removable cover rather than the foam itself, since memory foam by nature holds heat more than fiber or down fill. A washable outer cover gives some control over freshness and breathability compared with a sealed, non-removable cover. Sleepers who run hot and hug a body pillow closely for long stretches of the night should expect some warmth buildup from the foam core regardless of cover choice, which is typical for firm memory foam body pillows generally.

Care and practical fit

Because the pillowcase is washable and separate from the foam insert, day-to-day cleaning is manageable without needing to wash the entire foam core. The adjustable zippered fill is useful for dialing in firmness over the first few uses, since memory foam body pillows often need some fine-tuning to feel right for an individual's preferred sleep position. One practical note for anyone repositioning a body pillow through the night: firm memory foam fill is heavier than a fiber-filled body pillow of the same size, so expect more effort moving it compared with a lighter, softer alternative.

Value against the rest of the lineup

In this bolster and body pillow guide, this model ranks near the top, behind one higher-scoring competitor but ahead of several similarly sized alternatives. The adjustable fill and washable cover cover the core features shoppers look for in a body pillow at this length, and the firm support is a genuine differentiator from softer competitors in the same guide. Anyone who specifically wants a soft, huggable pillow rather than firm support should compare it against the lower-ranked, softer options in the same list before deciding. Side sleepers dealing with hip or back pain who need the pillow to actually hold its shape through the night are the ones most likely to appreciate the firmness here.

Frequently asked questions

Can I adjust how firm this pillow feels?

Yes, the memory foam fill is accessed through a zippered opening so you can add or remove foam to change the firmness and loft to your preference.

Is it suitable for pregnancy support?

The 20 by 54 inch length is designed to support the body from shoulder to knee while side sleeping, which is a common use case for pregnancy support, though it is not a pregnancy-specific curved design.

Is the cover removable for washing?

Yes, it uses a washable pillowcase that comes off separately from the foam insert, so you can wash the cover without putting the foam through a machine.

Is this a soft, huggable pillow?

No, it is built with firm support in mind, which suits sleepers who want the pillow to hold its shape rather than compress easily like a softer fiber-filled body pillow.
