Wedge Pillow

More than a gap filler. This triangular wedge closes the space between your mattress and headboard, footboard, or wall, so pillows, phones, and small items stop sliding underneath. Prop it against the headboard as a cushion for sitting up to read or watch TV, or set it at the foot of the bed to help keep pets from wandering under the bed.

Built to fit the gap. The tapered triangular shape fills gaps up to 6 inches deep, from a full-height edge down to a thin point, so it sits flush against your headboard, footboard, or frame instead of leaving a visible seam. Available in Twin, Full, Queen, and King to match your mattress width.

• A pocket built in. A durable side pocket keeps your phone, remote, or glasses within reach, so you're not digging around the edge of the mattress at midnight.
• Removable, washable cover. The velvet cover zips off the polyester-fill insert for easy care and machine or hand washing, so it stays looking and feeling new between washes.
• Backed by real support. Every Wedge Pillow carries OEKO-TEX Standard 100 certification, an independent test for harmful substances, with a 30-day return window if it isn't the right fit for your bed.

Things to Know About Wedge Pillow

What's the ideal height for a wedge pillow?

It depends on what you're using it for. Sleep-incline wedges, the kind you lie on top of, generally run 6 to 12 inches tall: a lower incline (6 to 8 inches) is more common for elevating the legs or a gentler upper-body lift, and a higher incline (10 to 12 inches) is more common for sitting up to read or watch TV. This Cool Bamboo wedge is a different type, a mattress gap filler and headboard cushion. It stands 10 inches tall at the peak and tapers to a 6-inch depth, sized to your bed (Twin 39", Full 54", Queen 60", King 76") rather than to a separate incline angle.

What are the benefits of this wedge pillow?

It closes the gap where your mattress meets your headboard or footboard, so things stop falling through. It gives you a stable, cushioned prop to lean against when you're sitting up in bed, best suited to back-lying or reclined use rather than side or stomach positions. And its shape and placement can help keep pets from squeezing underneath the bed frame.

How do people use a wedge pillow for intimacy?

Some couples use a wedge for added elevation and support, the same lift and stability it provides when you're propped up reading or watching TV.

What sizes are available?

Twin (39" long), Full (54"), Queen (60"), and King (76"), each 10 inches tall and 6 inches deep at the base, matched to your mattress width so the wedge sits flush at the edge of the bed.

What are the different types of wedge pillows, and which one is this?

Two different products both go by "wedge pillow." Sleep-incline wedges are single foam blocks you lie on top of to elevate your head, chest, or legs overnight, usually sized in inches and with a stated incline angle. Mattress gap fillers and headboard wedges, this product's type, are triangular bolsters placed at the edge of the mattress, against a headboard, footboard, or wall, used to close gaps and to prop yourself up while sitting rather than lying flat. If you're shopping for overnight incline support, for reflux, snoring, or elevating your legs, look for a sleep-incline wedge measured in inches with a stated angle. If you want to stop things from falling into the gap at your headboard and have a sturdy prop for sitting up, this is built for that.

Are there any downsides to be aware of?

A few worth knowing before you buy. The insert is a polyester fill rather than a solid foam block, so, like any pillow, it will compress and soften with regular use and may need an occasional fluff or reshape to maintain its full shape. It also has a fixed size for each bed width, so unlike stacking or adjustable wedge systems, you can't adjust the height. The side pocket is handy but sized for small items like a phone or remote, not a tablet or book. And because it's built as a bed accessory rather than an overnight lie-flat pillow, it's not the right pick if what you actually need is incline sleep support.

Real feedback from people who've tried lie-flat incline wedges for reflux or back support commonly points to one specific problem: a wedge that's too short for your torso, or an incline that's too steep, can create a hard bend at the waist instead of a gradual slope. If that's the discomfort you're trying to avoid, a torso-length incline wedge or bed risers under the frame tend to work better than a short, steep one.
