Robelle Heavy Duty Pool Pillows for Above Ground Pools — 4' x 8' Rectangular, 4-Pack (.22 mm Vinyl)

The Robelle 4 ft. x 8 ft. Heavy Duty Pool Pillow 4-Pack protects above-ground pool walls by absorbing ice pressure and keeping debris away from the center under your winter cover.

Winterizing an above-ground pool requires durable, reliable components — the Robelle pool pillows are engineered to reduce stress on pool walls and minimize water and debris accumulation beneath winter covers. Constructed from thicker .22 mm vinyl, these 4' x 8' pillows come four to a pack and are designed to be inflated partway, placed under the cover, and left to support the cover through freeze-thaw cycles and snowfall.

How do these pool pillows protect my pool during winter?

Robelle pillows create a raised cushion beneath the cover so ice pressure, snow load, and standing water push against the inflatable pillow instead of the pool wall. The pillow is built to yield under extreme pressure and will release before the pool wall takes damage.

• Absorbs and redistributes ice and snow loads away from vertical walls.
• Made from heavy-duty .22 mm vinyl — 37% heavier than standard materials.
• Designed to pop or deflate before forcing structural damage to the pool.

What size and quantity come in this pack, and how many do I need?

This pack contains four 4 ft. x 8 ft. rectangular pillows intended for typical above-ground pool layouts. The number you need depends on your pool diameter and cover shape; many customers use multiple pillows spaced evenly to support large covers and prevent water pooling.

• Four pillows per pack, each measuring 4' x 8'.
• Use two or more pillows for small pools; larger pools may need three or four spaced around the cover.
• Rectangular shape helps channel debris toward the pool edge for easier spring cleanup.

How should I inflate and install these winter pillows?

Partially inflate each pillow so it’s firm but still slightly compressible; overinflation increases risk that the valve will pop during freezing. Place pillows on the pool floor under the winter cover, evenly spaced to lift the cover and direct debris outward.

• Fill only halfway to two-thirds full — do not overfill.
• If the valve sticks, warm it briefly with a hair dryer to close securely.
• Position pillows so they create gentle peaks that shed water toward the sides.

What maintenance or care do these pillows need while stored or in use?

During winter, check that pillows remain properly seated under the cover and retain partial inflation. For storage, rinse any pool chemicals or debris off, allow to dry fully, and keep folded in a cool, dry place to prolong the vinyl life.

• Rinse and dry before storing to prevent mildew and material degradation.
• Store away from sharp objects and direct sunlight when not in use.
• Inspect valves and seams each season for wear and replace if damaged.

Who is this for: Robelle's heavy-duty pool pillow 4-pack is ideal for above-ground pool owners seeking a robust, reusable solution to minimize ice damage, reduce water pooling on covers, and simplify spring cleanup. It's a good match for anyone who prefers a proven, thicker-vinyl option from an experienced pool accessory brand and wants the convenience of multiple pillows in a single purchase.
