GORILLA GRIP Bed Wedge Pillow Gap Filler Twin/XL - Stops Pillows

In this review of the GORILLA GRIP Bed Wedge Pillow Gap Filler, the bottom line is simple: it is built for anyone who is tired of losing pillows, remotes or phones through the gap between a mattress and headboard or wall. The Twin/XL wedge fills gaps up to 6 in and uses hundreds of silicone grip dots to stay put, so the single biggest reason to buy is reliable gap coverage with non-slip performance. The pillow also doubles as a supportive foam wedge for sitting up or leg support, making it a practical bedside accessory.

Key Features

• Fills gaps up to 6 in: Designed to block the troublesome space between mattress and headboard so pillows and small items no longer slip through.
• Stay in place grip dots: Hundreds of silicone grip dots on the underside hold the wedge securely to the mattress and reduce shifting overnight.
• Thick high density foam: Constructed from 25D high density foam that rebounds to shape for consistent support when sitting or sleeping.
• Soft breathable cover: The 260gsm fabric cover is breathable and hypoallergenic, and it zips off for machine washing.
• Large side pockets: Two 6 in by 7 in pockets keep essentials like phones, remotes and glasses within easy reach.
• Certified safety standards: Foam meets CERTIPUR-US and OEKO-TEX standards so users can feel confident about product safety.

Who It's For

The wedge is ideal for people with platform beds, headboards or any sleep setup where a gap appears between the mattress and headboard or wall; it works particularly well for anyone who frequently sits up to read or watch shows and wants their pillow or essentials to stay in place. It also suits those who prefer a firmer, supportive wedge made from high density foam rather than a soft fill.

People who should look elsewhere include those who need a full mattress topper or therapeutic medical wedge prescribed for specific medical conditions, and shoppers who require a pillow wider than a Twin/XL size; this Twin model measures 39 in by 10 in by 6 in and is meant to sit across a single mattress width.
