Bed Gap Filler Pillow – 54 in Headboard Wedge with Side Pocket

This bed gap filler pillow closes the space between your headboard and mattress. Pillows, phones and remotes stop falling into the gap, and you get a firm, even edge to lean on when you read or watch TV in bed. It is a simple fix for beds with a slatted or gapped headboard, beds pushed against a wall, guest rooms and small bedrooms where every pillow counts.

Why You’ll Love the Bed Gap Filler

• No more lost pillows: the wedge sits behind your pillows so they stay on the bed instead of sliding behind it.
• Nothing drops behind the bed: phones, books and remotes stay on top of the mattress.
• Full-bed length: this bed gap filler is about 54 in (137 cm) long, the width of a standard full-size mattress.
• Side pocket: an outside pocket holds a phone, glasses or a small book at the bedside.
• Neat look: a simple triangular wedge in Gray or White that matches most bedding.

How It Works

1. Unpack the pillow — it ships compressed, so allow up to 24 hours for it to fully expand.
2. Slide the bed gap filler into the space between your headboard (or wall) and the top of the mattress, flat side against the headboard.
3. Put your sleeping pillows in front of it and use the side pocket for your phone or glasses.

FAQ

What bed size does this bed gap filler fit?

It is about 54 in long, the width of a full-size mattress. On a queen (60 in) or king (76 in) bed it covers most of the headboard side but not the full width.

How big a gap can it fill?

The wedge is about 5.9 in deep and 9.8 in tall. It works best for gaps up to a few inches; measure your gap before ordering.

Why does it arrive rolled up?

It is shipped compressed to save space. Unwrap it and allow up to 24 hours for it to return to its full shape.

Can I use it without a headboard?

Yes. Place it between the mattress and the wall to stop pillows falling behind the bed.

Is the cover removable?

The supplier does not state that the cover is removable or machine washable, so we do not promise it. Spot clean as needed.
