5 Common “Problems” with Split King Adjustable Beds—Solved

Jan 6, 2025 Jonas

At ESHINE, we take adjustable bases very seriously. In fact, my wife and I sleep on our ESHINE Adjustable Bases every night. Since their release in 2012, our split king-sized bases have become classics, garnering thousands of five-star reviews.

But there are still a lot of people who aren't very familiar with them. So if you have questions, you're not alone.

Are there any drawbacks to split king size beds? Do the two beds slide apart? Do you feel a gap in the center? Read on as our Showroom Manager, JONAS, answers the top 5“questions” customers have before buying an adjustable bed.

Jonas knows a thing or two about sleep. He's been in the business for nearly 20 years and has worked for some of the top mattress companies in the United States. There's no one better suited to solve your adjustable base problems than him.

For the rest of this blog, I sat down with JONAS to learn about the 5 most common adjustable bed base “problems” people ask him about. Why are “problems” in quotes? Because fortunately, these problems are easy to fix. And in many cases, once you've installed an adjustable bed base, you'll realize they're not problems at all.

Let's get right to the point!

1. The Gap Between Mattresses

The Issue:
One of the most common complaints about split king adjustable beds is the gap between the two mattresses. This gap can disrupt sleep comfort and potentially hinder intimacy for couples.

Solutions:

  1. Use a Mattress Bridge:
    A mattress bridge is a specially designed tool that fills the gap between two mattresses, creating a smooth, seamless sleeping surface.

    • Benefits: Affordable, easy to install, and removable.
    • Tip: Invest in a high-quality bridge for durability and maximum comfort.
  2. Use a King-Sized Fitted Sheet:
    Cover both mattresses with a king-sized fitted sheet to hold them together and minimize any movement that could create gaps.

    • Pro Tip: Choose fitted sheets with elastic edges for a snug fit that keeps the mattresses aligned.
  3. Opt for a Split-Top Mattress:
    Eshine will offer "split-top" or "flex-top" mattresses that look and feel like one mattress but allow independent adjustability. This is a great choice for those highly sensitive to the gap issue.

  4. Regularly Adjust Mattress Alignment:
    Over time, the two mattresses may shift due to frequent adjustments. Manually aligning them periodically ensures they stay close together, reducing the gap.

Things to Keep in Mind:

  • Avoid overly thick or rigid mattress bridges, as they may affect the comfort of your sleeping surface.
  • If the gap is a significant concern, a split-top mattress might be the ultimate solution to eliminate the issue entirely.

2. Sliding Mattresses

The Issue:
Mattresses on split king adjustable beds can sometimes slide apart when the base is adjusted, especially with lightweight or thinner mattresses. This can disrupt sleep and make the bed feel less stable.

Solutions:

  1. Anti-Slip Pads:
    Placing non-slip pads between the mattress and the base can help keep the mattress firmly in place.

    • How to Use: These pads are typically made of rubber or a similar grippy material and are easy to position under the mattress.
    • Benefits: Inexpensive, effective, and requires no permanent changes to the bed.
  2. Retainer Bars:
    Many adjustable bases come equipped with retainer bars at the foot of the bed to hold mattresses securely. If your base doesn’t have them, consider upgrading to one that does.

    • Tip: Ensure the retainer bars are sturdy and properly installed for optimal performance.
  3. Mattress Straps:
    Mattress straps or Velcro bands can be used to fasten the two mattresses together, preventing them from sliding apart.

    • How to Use: Wrap the strap around the mattresses and secure them tightly.
    • Bonus: This method can also help reduce the gap between mattresses.
  4. Heavier Mattress Options:
    Lightweight mattresses are more prone to sliding. If feasible, opt for a heavier mattress that is less likely to shift during adjustments.

    • Example: Hybrid or latex mattresses often stay in place better than all-foam models.
  5. Adjustable Base with Built-In Anti-Slip Features:
    Our premium adjustable bases come with anti-slip technology, such as textured surfaces or integrated grips. Investing in a base with these features can eliminate sliding issues altogether.

Things to Keep in Mind:

  • If using anti-slip pads, ensure they are compatible with your mattress material to avoid damage.
  • Regularly check and adjust retainer bars or straps to maintain effectiveness.

With these practical solutions, you can prevent your mattresses from sliding and enjoy a stable and comfortable sleep experience on your split king adjustable bed.

3. Difficulty Syncing Movements

The Issue:
In a split king bed, the two sides may not move in sync, which can create operational difficulties. This misalignment can be frustrating, especially when adjusting the bed’s position.

Solutions:

  1. Activate Sync Mode:
    Most adjustable beds come with a sync function that allows both sides to move simultaneously, eliminating the issue of misalignment.

    • HOW TO USE: Use the Sync Cord for one-touch control to easily synchronize both beds!
  2. Check Power Connections:
    If syncing issues persist, it may be due to a loose or damaged power connection. Sometimes, power issues can interfere with the synchronization feature.

    • How to Fix: Disconnect the power, check all connections, and ensure that everything is securely plugged in.
  3. Contact Technical Support:
    If the syncing issue continues, reach out to the EHSINE’s technical support team. We will guide you through troubleshooting steps or schedule a technician to inspect the bed.

    • Tip: Provide the bed’s model and serial number to help the support team address your issue more efficiently.

4. Bedding Challenges

The Issue:
Finding bedding for a split king bed can be a challenge. Standard king-sized sheets or twin XL sheets often don’t fit properly, causing discomfort or the need for constant adjustments.

Solutions:

Split King Bedding Sets:
The easiest solution is to purchase sheets specifically designed for split king beds. These sets usually include two twin XL fitted sheets for the mattresses and a shared top sheet.

    • How to Use: Simply purchase a split king sheet set, ensuring that each mattress has its own fitted sheet, while the top sheet is large enough to cover both.
    • Benefits: These sets provide a snug fit, eliminating the need for constant adjustments or slipping sheets.

5. Noise During Adjustment

The Issue:
The motor or frame of a split king adjustable bed may produce noise when adjusting, which can disrupt the sleep environment, especially for those sensitive to sound.

Solutions:

  1. Regular Maintenance:
    Performing regular maintenance on your adjustable bed can help reduce noise caused by the motor or frame.

    • How to Fix: Periodically check for loose bolts or screws and tighten them. Loose components can result in rattling sounds during adjustments.
    • Lubrication: Apply a light lubricant to the moving parts such as joints or hinges. This helps reduce friction and noise.
    • Tip: Conduct maintenance every few months to keep the bed functioning smoothly and quietly.
  2. Opt for Silent Models:
    If noise continues to be an issue, consider upgrading to a higher-end adjustable bed with a quieter motor.

    • Why Choose Silent Models: High-end models are typically designed with silent motors and mechanisms that reduce noise during bed adjustments.
    • Each Eshine adjustable bed is powered by a German OKIN motor for high-end quality and quiet operation, so you can enjoy a good night's sleep!
