GORILLA GRIP Bed Wedge Pillow Headboard Gap Filler - Stops Slipping

In this review the GORILLA GRIP Bed Wedge Pillow Headboard Gap Filler is presented as a practical solution for anyone tired of losing pillows and small items down the gap between mattress and headboard. The biggest reason to buy is straightforward: it fills mattress gaps up to 6 in so pillows, remotes and glasses stay put while adding a comfortable, supportive foam surface for sitting up in bed. The review focuses on real use, comfort and whether the stay-in-place grip dots and side pockets actually work as advertised.

Key Features

• Gap filling design: Fills mattress gaps up to 6 in wide so pillows and small bedside items no longer slip through the space behind a mattress.
• Stay-in-place grip dots: Hundreds of silicone grip dots on the underside create friction with the mattress and help the wedge resist shifting during use.
• Supportive high density foam: Made from 25D high density foam that rebounds to shape, offering medium-firm support for sitting up, reading or leg elevation.
• Soft breathable cover: The 260gsm fabric cover feels softer than standard pillowcases, is hypoallergenic and includes a zipper for easy machine washing.
• Side storage pockets: Large 6 in by 7 in pockets on each side keep phones, remotes and glasses within reach while creating a neater bedside area.
• Certifications: Foam meets CERTIPUR-US and OEKO-TEX standards so users can feel confident in product safety and materials.

Who It's For

This wedge pillow is ideal for people who sleep or sit up against a headboard and frequently lose pillows, remotes or reading glasses down the gap; it also works well for those who like a firmer, supportive surface for reading or watching media in bed. The full size span and firm 25D foam suit couples or single sleepers with larger mattresses who want an across-the-top solution.

People who need a very soft, plush pillow for side sleeping or who require a medical-grade positioning device should look elsewhere; while supportive, this product is a wedge gap filler and bedside organizer rather than a specialty medical aid for complex conditions.

Pros & Cons

Pros

• Effective gap coverage that prevents pillows and small items from falling behind the mattress.
• Silicone grip dots keep the wedge from sliding so it stays aligned with the mattress during use.
• Comfortable, resilient 25D high density foam provides firm support and returns to shape night after night.
• Convenient side pockets add practical bedside storage without extra furniture.

Cons

• The wedge is on the firmer side and may feel too firm for users preferring plush cushioning.
• Designed to fill gaps up to 6 in; larger gaps or unusual headboard clearance may still allow movement.
