Feeling frustrated by that annoying gap between your mattress and the headboard? I know the feeling all too well. It’s where pillows vanish into the abyss, remote controls disappear, and even small pets can find themselves in a predicament. This persistent void isn’t just inconvenient; it can disrupt sleep and make your bedroom feel less comfortable and tidy. Finding a reliable solution for this problem was a game-changer for me.

What to Look for When Choosing a Bed Gap Filler
If you’ve ever lost something important down the side or back of your bed, you understand why a bed gap filler is more than just a luxury – it’s a necessity for a truly restful and organized sleeping space. This type of product is ideal for anyone whose bed doesn’t sit flush against the headboard or wall, or even those who have pushed two mattresses together and want to eliminate the middle seam. It’s particularly helpful for side sleepers whose arms might slip into the gap, parents whose kids’ toys end up lost, or pet owners whose furry friends like to snuggle near the edge and could potentially fall.
However, a bed gap filler might not be necessary if your bed setup has no gaps at all, or if you use a platform bed without a headboard where items can’t easily fall. When considering which mattress extender to purchase, you’ll want to think about a few key things: the exact size of the gap you need to fill (length, width, and height), the material and density of the filler (you want something supportive but comfortable), the ease of cleaning the cover, and whether it’s durable enough to maintain its shape over time. Ignoring these factors can lead to buying a filler that doesn’t fit, collapses easily, or is difficult to keep clean, leaving you right back where you started.

Introducing the DEEPSHARK BGF Mattress Extender
Enter the DEEPSHARK Bed Gap Filler for King Mattress, model BGF. This product promises to effectively close that troublesome space at the head of your bed, preventing items from falling and essentially extending your usable mattress surface. What you get is a high-density sponge filler specifically sized for King beds (this particular model is 78″×4″×12″), encased in a removable and washable linen cover.
This bed space filler is designed for King mattress owners who struggle with gaps against a headboard, wall, or even between two pushed-together mattresses. It’s likely less suitable for those who need a filler for a different mattress size, although DEEPSHARK does offer various dimensions. Compared to generic foam fillers, the DEEPSHARK distinguishes itself with a stated high 45D density sponge and a focus on providing specific sizes for different mattress widths.
Here are some quick pros and cons based on the product description and user experiences:
Pros:
* Uses high-density 45D sponge for better resilience than standard foam.
* Comes with a soft, breathable, removable, and washable linen cover.
* Available in a wide range of sizes for different beds and gaps.
* Offers a straightforward solution to a common bedroom problem.
* Customer service seems responsive based on feedback.
Cons:
* The foam requires expansion after vacuum sealing, which isn’t always complete on its own and may require extra steps (like steaming).
* Some users report slight size discrepancies, particularly with the width, even after expansion.
* Initial appearance out of the box can be concerning due to compression.
Diving into the DEEPSHARK BGF’s Key Attributes and Advantages
Having integrated the DEEPSHARK Bed Gap Filler for King Mattress into my own bedroom setup for a significant period, I’ve had ample time to appreciate its design and functionality, while also noting some quirks. Let’s break down the core features and the tangible benefits they provide.
The High-Density 45D Sponge Core
At the heart of the DEEPSHARK BGF is its claim of using a high-density 45D sponge. This isn’t just a number; it refers to the foam’s density, which directly impacts its durability and supportiveness. Lower density foams tend to compress easily and may not fully spring back, especially when used in a high-pressure area like the edge of a mattress where you might lean or sit. The 45D rating suggests a much more robust and resilient material designed to withstand pressure and maintain its shape over time.
In practice, this means that when the mattress extender is properly expanded, it provides a firm, supportive surface that seamlessly bridges the gap. It doesn’t feel flimsy or like it will instantly collapse if you place a pillow on it or accidentally roll onto it slightly. This supportiveness is key to solving the core problem; a weak filler would just let things fall down anyway.
However, and this is a point echoed in user feedback, achieving that full, advertised expansion from the compressed packaging can sometimes be a hurdle. The instructions mention waiting 48-72 hours, but based on my experience and others, this isn’t always sufficient, particularly for the ends or edges of the foam. It seems the deep compression for shipping can sometimes make the foam hesitant to fully recover on its own. This is where the ‘disadvantage’ comes in – you might need to employ methods like gentle steaming (as suggested by other users) to help the foam reach its intended dimensions and firmness. While this extra step isn’t ideal, the underlying quality of the 45D foam itself is evident once it *does* fully expand, providing that desired firm support.
Tailored Size Selection
One of the appealing aspects of the DEEPSHARK Bed Gap Filler line is the variety of sizes available. This review focuses on the 78″×4″×12″ King size, which is designed to span the width of a standard King mattress. The availability of different widths (39″, 54″, 60″, 78″) and even depth/height options allows customers to find a fit tailored to their specific bed size and gap dimensions.
For the King size model, the 78-inch length is crucial for fitting across the width of the bed without leaving gaps at the sides. The 4-inch width is designed to fill a gap of that measurement, while the 12-inch height should align with most standard mattress heights, creating a flush surface. This focus on specific dimensions is a clear benefit, allowing for a more integrated and less noticeable solution compared to trying to make a generic size work.
That said, the reports of slight size discrepancies, particularly regarding the width not fully expanding to the advertised 4 inches for some users, are worth noting. This seems linked to the expansion issue mentioned earlier. While the *intent* is to provide a precise fit, the reality of foam expansion post-compression can sometimes fall slightly short, which is a minor drawback if you have a very specific gap size you’re trying to match perfectly. Despite this, the principle of offering tailored sizes is a significant advantage over a one-size-fits-all approach.
The Practical and Pleasant Linen Cover
The exterior of the DEEPSHARK BGF features a cover made from breathable linen fabric. Material choice here is important. Linen is known for its durability, breathability, and pleasant texture. Unlike some synthetic covers that can feel cheap or cause sweating, the linen feels soft and skin-friendly, which matters when it’s positioned right next to where you sleep.
The cover also boasts a durable zipper, a seemingly small detail but a vital one for longevity and practicality. This design makes the cover easily removable, which is essential because, let’s face it, the area around your bed can get dusty or occasionally encounter spills. The ability to simply unzip the cover and wash it (the product care instructions suggest tumble drying on low heat or air drying) ensures that your bed crack filler stays clean and hygienic, contributing to a healthier sleep environment. This easy-cleaning design adds significant value and convenience to the product.
Versatile Application Beyond the Headboard
While commonly referred to as a “bed gap filler for headboard,” the DEEPSHARK mattress extender is designed for versatility. Its primary use is indeed the gap between your mattress and the headboard, preventing items like pillows from slipping down. However, its utility extends to other common scenarios.
It can be used as a “mattress extender” in the sense that it adds a few inches of usable, stable surface at the top of your bed, making the sleeping area feel larger and more complete. It’s also effective at filling the space between a mattress and a wall, which can happen in certain room layouts or with adjustable bases. Furthermore, for those who push two twin or twin XL mattresses together to create a larger bed, a narrower version of this filler can be used to bridge the gap in the middle, creating a more unified surface. This multi-purpose capability makes the bed space filler a practical tool for various bedroom configurations where unwanted gaps exist. The benefit is always the same: preventing lost items, eliminating pinch points, and creating a cleaner, more contiguous sleeping area.
Commitment to Quality and Customer Service
The product description highlights a commitment to providing high-quality products and premium customer service. While no product is without its potential issues (like the expansion challenge), the company’s willingness to address concerns, such as sending the wrong size or dealing with expansion problems, as noted in user reviews, is a significant plus. Knowing that the company stands behind their bed gap filler and is responsive to customer feedback instills confidence in the purchase. While encountering an issue like incomplete expansion can be frustrating, a company that actively works to resolve it turns a potential negative experience into a positive interaction, reinforcing the overall value proposition of the DEEPSHARK BGF.
What Real Users Are Saying
After sifting through comments from other buyers, a clear picture emerges. Many users agree that this bed gap filler effectively solves the problem of items falling behind the bed, offering great value and quality for the price once in place. However, a consistent theme is the foam’s expansion process. While it arrives vacuum-sealed, which is expected for shipping, the foam doesn’t always fully recover its shape, particularly the edges, within the stated 48-72 hours. Several inventive users discovered that using steam from an iron or a steamer greatly helps the high-density foam expand completely and regain its intended dimensions, even addressing areas that appeared permanently flattened or discolored. There were a few instances of receiving the incorrect size initially, but customers reported that the company and Amazon were helpful in facilitating returns and replacements, demonstrating decent customer support when issues arise. Despite the potential initial hassle with expansion, the sentiment is largely positive once the DEEPSHARK BGF is fully expanded and in place.
Final Thoughts on Reclaiming Your Bed Space
That gap at the head of your bed doesn’t have to be a black hole for your essentials anymore. Losing pillows, remotes, or having things just disappear into that space is a daily frustration that detracts from the comfort and functionality of your bedroom. The DEEPSHARK Bed Gap Filler for King Mattress offers a compelling solution. With its high-density foam designed for durability and support, a convenient washable cover, and a range of sizes aimed at providing a good fit, it addresses the problem head-on. While you might need a little patience or even a bit of steam to help it reach its full potential after shipping, the end result is a seamless extension of your mattress that keeps everything where it belongs. If you’re tired of things falling into the void, this mattress extender is definitely worth considering. To see the various sizes and learn more, click here.
