GJQ 4x15Ft Pool Pillow for Above-Ground Pools — Heavy-Duty PVC Inflatable Winter Cover Cushion

GJQ's 4x15Ft Pool Pillow is an inflatable air cushion designed to sit under an above-ground pool cover and relieve ice, snow and water pressure so your pool walls and cover stay protected through winter.

When freezing temperatures, snow and rain collect on a covered above-ground pool, expanding ice and pooled water can strain the liner and frame. The GJQ 4x15Ft Pool Pillow installs at the pool center to create a low spot for meltwater and snow to drain toward, and it pushes expanding ice away from pool walls—reducing the risk of rips, bulges or cover sagging. Built from cold-resistant PVC with reinforced seams, this inflatable solution is sized to serve larger pools and is simple to set up or remove each season.

How does the pool pillow protect my above-ground pool during winter?

The pillow acts as a pressure absorber between the cover and pool surface. By creating a controlled bulge in the cover, it guides meltwater and snow away from the edges and spreads ice pressure across the pillow rather than on the liner or walls.

• Offsets freeze expansion to prevent wall deformation.
• Channels water to the center to avoid edge pooling and cover collapse.
• Reduces stress on seams and liner attachment points.

Is it durable enough for cold temperatures and harsh winter conditions?

Yes — GJQ designed the pillow from 0.3mm cold-resistant PVC and double-sealed edges to resist tearing and leakage in low temperatures. It is rated for use in temperatures down to about -10° F (-25° C), making it suitable for many cold-climate winterizations.

• 0.3mm PVC withstands cold without becoming brittle.
• Double-sealed edge reduces leak and tear risk from ice.
• Recommended 70% inflation leaves room for ice expansion.

How do I install and secure the GJQ pool air pillow?

Installation is quick and requires only a common electric air pump (not included). Inflate the pillow to roughly 70% to leave expansion space, position it in the pool center under the cover, and attach the included fixing cords through the four edge holes to anchor the pillow.

• Inflate with a standard household air pump (not supplied).
• Use the four included 4m cords to tie pillow to center or return fittings.
• Install time: about ten minutes for a single person.

What pool sizes and situations are best for this 4x15Ft pillow?

The 4x15Ft pillow is intended for larger above-ground pools where a bigger center cushion helps distribute ice pressure and manage more snow or rain. It works with most standard above-ground pool covers and is especially useful when heavy snowfall or deep freezes are expected.

• Suitable for most above-ground pools, especially wider diameters.
• Helpful where heavy snow or runoff may overload the cover.
• Also assists in keeping leaves and debris from accumulating in the center.

Who is this for? Homeowners with above-ground pools who winterize their pools and want an affordable, low-effort way to reduce damage risk caused by ice expansion, snow load and cover sagging. It’s a practical accessory for people living in cold regions, owners of larger pools that need a bigger central relief, and anyone looking for a simple seasonal addition that installs quickly and stores compactly in summer.
