Why Sleep Number Split King Gap Filler Is Necessary
From my experience, the Sleep Number Split King Gap Filler is absolutely essential for anyone using a split king bed. Since the bed consists of two separate mattresses side by side, there’s naturally a gap between them. This gap can be uncomfortable, causing me to feel like I’m sinking into the middle or even risking small items falling between the mattresses. The gap filler effectively bridges this space, creating a seamless sleeping surface that feels more like one unified bed.
Another reason I find the gap filler necessary is that it enhances both comfort and support. Without it, the middle gap can disrupt my sleep posture and cause unnecessary pressure points. The filler provides extra cushioning and stability, which helps me maintain proper alignment throughout the night. Plus, it keeps the sheets in place better, so I don’t have to constantly adjust them. Overall, the Sleep Number Split King Gap Filler has made my sleep experience much more restful and enjoyable.
My Buying Guides on Sleep Number Split King Gap Filler
When I first decided to get a Sleep Number Split King bed, one of the small but annoying issues I encountered was the gap between the two mattresses. That’s where a Sleep Number Split King Gap Filler came in handy. If you’re considering one, here’s my guide based on my personal experience and what I learned along the way.
Why Do You Need a Split King Gap Filler?
The Split King bed consists of two twin XL mattresses placed side-by-side. While this setup offers personalized comfort, it also creates a gap between the mattresses. I found that gap uncomfortable—it could catch sheets, pillows, or even your arm during sleep. A gap filler bridges that space, giving you a more seamless sleeping surface and improving comfort.
Types of Sleep Number Split King Gap Fillers
When I looked for a gap filler, I noticed a few main types:
- Foam Wedge Gap Fillers: These are typically made of high-density foam and fit snugly between the mattresses. They are firm yet comfortable.
- Memory Foam Gap Fillers: These contour more closely to your body shape, adding a bit of extra cushioning.
- Adjustable or Inflatable Gap Fillers: Less common, but some products allow you to adjust firmness or thickness.
I personally went with a high-density foam wedge because it was durable and easy to install.
Key Features to Consider
Here are the features I focused on while choosing my gap filler:
- Size and Fit: It’s crucial that the gap filler matches the width and length of the Split King gap. Most are designed specifically for this, but double-check dimensions.
- Material Quality: I wanted something durable that wouldn’t flatten over time. High-density foam or memory foam are good options.
- Ease of Installation: I appreciated a gap filler that was simple to place and remove when changing sheets.
- Cover Material: Some come with removable, washable covers which help keep things clean.
- Firmness Level: Think about your preference—whether you want the gap filler to be very firm or slightly cushioned.
My Installation Tips
Installing the gap filler was straightforward, but here are a few things I learned:
- Make sure both mattresses are perfectly aligned before inserting the gap filler.
- Place the gap filler flat so it fills the entire gap without bending.
- Use fitted sheets designed for Split King beds; some sheets have a divider to hold the gap filler in place.
- If you find the gap filler shifts during the night, try securing it with Velcro strips or non-slip pads.
Where to Buy and Pricing
I found gap fillers online through Sleep Number’s official store as well as third-party retailers like Amazon. Prices can vary from $50 to $150 depending on materials and brand. I recommend reading customer reviews to ensure you’re getting a quality product.
Final Thoughts
The Sleep Number Split King Gap Filler made a noticeable difference in my sleep comfort. It eliminated that annoying gap and made the bed feel like one unified mattress. If you have a Split King, I highly suggest getting a gap filler—it’s a small investment with a big payoff. Just remember to consider size, material, and ease of use when making your choice.
I hope my experience helps you find the perfect gap filler for your Sleep Number Split King bed!
