count on for you to rest your weary body, but there does come a time when you should switch it for a new one. Beyond the dreaded sag of an old coil mattress there are other factors that answer the question “When should I replace my mattress”? Even a memory foam mattress will need to be replaced for various reasons.
Sleep time is most important for all to have the best health as it refreshes the body and mind to function to its capacity. Giving each their own split-king mattress, placed side by side to create a king size bed, will assure a custom sleep surface fitted to each individual to allow for the best rest possible.

I. What is a Split King
It is difficult enough for a couple to get through the daytime hours without having a topical heated debate over some matter – big or small. A split king puts a stop to any bickering about mattress comfort from disturbing each bed partner’s ability to drift off to dreamland.

A. Two Mattresses Equals One
The split king bed is simply two separate mattresses placed side-by-side. This creates the same dimensions of sleep space that a conventional King bed, sized 76-inches wide by 80-inches long, allows.
The mattresses used for a split king are two 38-inches wide by 80-inches long Twin XLs. These mattresses originated on University campuses created to allow extra tall athletes a bed long enough to accommodate their sleep needs. Eventually college dorms transitioned to providing the Twin XL for all students to make dorm life easier for all. What was created for dorm life has been realized to provide a more comfortable home life as well. Parents are opting for the Twin XL instead of a common Twin bed to allow for a child to have ample growing room.
B. Perfect Choice for Couples
Realizing that two Twin XLs make up the same footprint as a King mattress has allowed for mates to place the two Twin XLs together to create a King size sleep space. This allows for each to have a mattress surface that provides individual wants and needs – providing sleep comfort for all.
II. The Split King Adjustable Bed Base
A traditional King bed has been traditionally manufactured with two separate bases to aid in moving. As even the older spring-coil mattresses may be a bit bendable around corners, the solid base needed to be broken up to be moved easily into a home and room. The split King base – as with the split King mattress – is comprised of two Twin XL bases.
The adjustable base is an excellent choice to use for the split King, as it makes the perfect mate for the customized comfort that the split mattress provides each bed mate. Two Twin XL adjustable bases placed side-by-side can be synced together for those using one King mattress, or used independently for the split King mattress bed.
III. Split King Mattress Bed Benefits
The split King has many benefits for couples longing for peaceful coexistence in bed. From simply making a home move easier to aiding in individualized health and well-being needs, opting to have a split King instead of one mattress can help bring harmony to the abode.
A. Resolves Home Moving Issues
The very large sized King mattress can be very awkward to move. Whether a stiffer coil spring bed or a newer, more bendable, memory foam, the immense size of the King mattress can impede on a simple move from one room, or home, to another.
Once the comfy memory King sized foam mattress has been initially unboxed and placed it can be a heavy chore to need to move through doorways, around corners, and up and down stairs. Whereas using two Twin XLs to make up a King-sized bed will also make any needed move much easier. Just as the split base is made for moving one will also have two smaller sections to move – rather than the one immense King mattress.
B. Helps Stop Snoring
So many snoring partners causing a night of interrupted sleep for their mates have also triggered endless arguments and even forced one to move to another bedroom, or worse, the couch. Placing the split King on individual adjustable bases will allow for the non-snoring partner to stop the snoring by raising the culprit’s head to a position that will stop the offensive noise.
C. Ends Motion Transfer Disturbance
The split King bed is perfect for those whose sleep is constantly interrupted by a partner who tosses and turns throughout the night, or is constantly getting in and out of bed. When sleeping on a single King mattress, no matter how good the bed may be as far as feeling motion transfer, one can still be wakened by another who is in continual motion. The split King allows for each to have their own mattress and not feel any movement from the other in bed with them.
D. Allows for Personal Space
Personal space is a craved importance to most. This is essential to have in bed as it is out of bed. Yes, cuddling time under the covers is critical to a harmonious relationship, but so is giving each other their needed space.
When bed time arrives so do different rituals. The split King on an adjustable base will allow for one partner to feel a soothing massage while the other enjoys the relief of pain that the zero-gravity position provides. While one wants to sit up to do some last-minute work, or read, the bed mate can easily get into his or her own comfortable position for drifting off to slumber.

E. Accommodates Separate Sleep Preferences
Side, back and stomach sleepers have different preferences for mattresses. A split King allows for custom needs. While one partner will want a bed firm as a rock, the other may want a plusher top to sink into. The back or stomach sleeper may relish the firmness of a mattress whereas the side sleeper may want a more luxe version or even an added plush mattress topper.
If one bed mate is ill or congested he or she can raise the head of their split side atop an adjustable base, without disturbing the other. When one is nursing a painful leg in a raised position, a mate can still sleep peacefully in a flat position.
IV. Split King Bedding
A split king bed will need slightly different bedding than for a traditional King. The two separate mattresses making up the one bed will each need their own fitted bed sheet. Other than the fitted sheets the split mattresses can be made up as one bed with a single King top sheet along with single quilt and duvet. If one mate gets colder than the other, he or she has the option of adding extra blankets to their own side.
V. Conclusion
Enjoying a split King bed can be the answer to the dreams of achieving a great sleep while also enjoying the closeness of a partner in bed. Finally, there is an answer to getting sleep even with a partner who tosses and turns all night.
