SPLIT FIRMNESSUpdated 2 years ago

Looking for a mattress with two firmnesses in one mattress? You might be wondering if Spindle offers a split firmness mattress. The answer is yes – but only in king size.

Spindle now offers a split firmness mattress, so you can each have your own level of firmness on your side of the bed. Our 10" Organic Latex Mattress is made with three layers of latex, but we can split the firmness so that you have two different levels of firmness on each side of the mattress. This is perfect for couples who have different preferences, or for anyone who wants the flexibility to change the firmness level down the road.


Keep in mind that a split firmness mattress is not right for everyone. If you’re not sure whether this type of mattress is right for you, be sure to consult with Spindle before making your purchase.


When you purchase a mattress with different firmness levels on each side, you may notice a slight change in feel in the middle of the mattress. Some people report feeling a ridge or dip, while others say they feel as if they are sinking down or rolling into the middle of the mattress. This has not been an issue for the vast majority of customers who sleep on a king-sized mattress with a split firmness, but it is something to be aware of. Additionally, there is potential for minor height variance between each side of the mattress because of the natural tolerance, or acceptable plus or minus, in latex. So, one side of the mattress could be a 1/4" short and the other side a 1/4" tall, leading to a 1/2" difference between each side. Again, this has not been a problem for most people, but it is something to be aware of.

The cover of your mattress is important for keeping all the layers in place, but you may need to unzip it and reposition the layers of latex from time to time if you feel a dip in the middle. This isn't a common occurrence, but something to be aware of.

While these are not typical issues that people experience, we want to give you the option, and the ability to make a well-informed decision without the hype.


We know what you're thinking, why not just get a king size mattress? Well, the answer is not that simple. If you get a king, the mattress will move in unison. If you have two people who want different settings on the adjustable bed, then a king simply won't work. You'll be constantly adjusting to accommodate the other person, and it'll just be a pain. With two twin extra longs, each person can have their own preferences. One person can sit up and read while the other can fall asleep in a zero-gravity position so each person can adjust the bed to their own liking. No more fighting over who gets to control the remote! So, if you and your partner are looking for an adjustable bed, we recommend getting two twin XLs instead of a split king. It'll save you a lot of headaches in the long run. This way, each person can adjust the bed to their liking without affecting the other person.

Please note that two twin extra-long mattresses equal a king size mattress.


We personally don't recommend splitting a queen-size mattress, as most people who sleep on a queen-size or smaller mattress share the middle. This can be uncomfortable for most people, as each sleeper is confined to a smaller sleep area. With a split queen, you only have 30" of space to yourself. This is 8" narrower than a twin. Most people wouldn't be comfortable sleeping on something so narrow.
