In fact, users reveal that they help with pain relief and minimize extensive snoring. However, they are not 100% perfect; below are the six most common downsides of adjustable split king adjustable beds.

Sliding Mattresses

One of the primary challenges with split king adjustable beds is the moving mattresses. While most manufacturers guarantee that their split king mattresses will not move, that is not always the case. The mattresses will move when you toss and turn in your sleep. Such movements can make you uncomfortable and disrupt your sleep, especially if you have to wake up to adjust them. No couple wants to sleep with a giant gap between them.

The Bed Needs Special Sheets

Do you know that regular mattress sheets are not recommended for split adjustable king beds? The beds require special mattress sheets that will not keep coming off as the mattresses move. Note that these beds have separate mattresses, unlike the regular beds.

You need to purchase unique twin XL fitted sheets for the mattresses. But finding these sheets is not always easy because they are not in most stores, and they come at an added fee compared to regular mattresses. More so, after purchasing the special sheets, you must maintain and store them right.

Loud Mechanisms

Another problem with split king adjustable beds is their loud mechanisms. Most people purchasing these beds for the first time do not realize that this could be a problem. But the truth is mechanisms become noisy over time. The funny mechanism sounds will impact your sleep negatively.

Every time your partner turns or adjusts their side of the bed, the sound will make you uncomfortable to the extent of waking up. If your partner loves to change sleeping positions severally or weighs several pounds that exact lots of pressure on the bed mechanisms, you will not enjoy continuous quality sleep.

Split King Adjustable Beds Are a Little Pricey

Most manufacturers attribute the price to the beds' comfort and health benefits. The bed frames are also more costly than regular ones. Don't forget that once you have purchased the bed, you will also need special sheets, which means spending more money.

Frame Complications

You may also have difficulty finding a compatible headboard for your split king adjustable beds. Headboards are an easy and efficient way to customize your bed frame for an attractive look; even the most comfortable beds will benefit from a headboard. However, finding suitable headboards for the split adjustable king beds and fixing them is not easy.
