Sacroiliac Joint Pain and Mattresses

When my SI joints were at their worst, they were extremely sensitive to the kind of surface I was resting on.

Of course, in the midst of my problem, the mattress I’d loved for about 10 years finally wore out. And it wore out bad.

Now that I’m doing better, it’s almost hard to remember how sensitive I was.

At the time, all I knew was that a mattress that was too soft, or worn out, would cause my SI joints to rotate out of place and lock up as my body sank down, finding a new equilibrium.

And a mattress that was too hard, paradoxically, would do the same thing– it would kind of force my body to adapt to a position that it didn’t really “want” to, and somehow my SI joints would lock up then, as well.

It was awful– before I found my new mattress I didn’t even want to go to bed at night.

What I really needed to find was a mattress that had just the right amount of cushioning on top to protect my joints, but was still firm enough overall that my body wouldn’t sink in.

And boy, did I have a hard time.

I don’t want to tell you how many mattresses I tried or money I spent before I found the right thing.  Let’s just say that, when you are going through a major department store/mattress chain, the process is going to be expensive– expect delivery fees– and the most you will ever be able to hope for, if you have second thoughts, is an exchange.

At one point I was so desperate, I wondered if maybe I could just live my life on an air mattress, since that seemed to be the most easily customizable in terms of firmness.

However, it turns out there are much better, updated ways to do your mattress shopping.

I ultimately did some research, and it turns out that now that we’re in the 2010’s 2020’s, there are actually some much better ways to do your mattress shopping.

There are a few new mattress start-ups which operate almost entirely online:

Casper, Leesa, and Tuft and Needle all offer free in-home trials of up to 100 days.  If you change your mind during this period, they basically donate your mattress to charity and give you a refund.

Personally, I tried both the Casper and the Leesa, until I realized that a super-soft foam mattress wasn’t for me.  However, if firmness isn’t a significant concern for you (everybody’s different), I would recommend giving them a try.  I found the customer service at both companies to be easy to deal with, and had no trouble arranging my returns and refunds.

When I finally found the perfect mattress:

Ultimately, I ended up finding the perfect mattress through a company called Room and Board.  I was able to go in to the Boston store and pick out the mattress I wanted (I went with the Innerspring Firm).

I’ve had it for two years now, and it’s been exactly what I was looking for.  It’s firm enough that my body doesn’t sink in too far, yet with just enough cushioning so that I also don’t feel any specific tender points.  It’s been a lifesaver.

I do have to say that since I bought it, some of the cushioning on top has become a teeny bit condensed.  However, I’ve made sure to rotate the mattress when I feel this starting to happen, and so far it’s evened out and hasn’t changed the overall feel of the mattress.

Room and Board’s great customer service policies also added to my positive experience.  If you happen to live near a store, you can actually try the mattress out in person.  Then, regardless of whether you’re ordering from the store or ordering online, they offer a 120-night in home trial.  (You do have to pay a $90 flat-rate shipping fee, which would have covered the cost of a return if I needed to make one).

However, it was totally worth it in my case.  I found the perfect mattress at a great store, with much more customer-friendly policies.  And of course I didn’t need to make a return, because I totally love my mattress!


As I learned throughout all of my misadventures mattress shopping, it’s really important to make sure that your mattress is supported by the surface it’s on.  I use this Sealy box spring, and am happy with the level of support it gives my mattress.


I also find that the height of the mattress makes a difference getting in and out of bed.  I use my 11″ Room and Board mattress directly on the 9″ box spring on the floor.  This makes the whole thing about 20″, and I find it’s just the perfect height for me to get in an out comfortably.  (I’m 5’4″, so this is just to give you an idea!  Do what works for you!).


So, if you are thinking of replacing your mattress, I definitely recommend you look into one of these newer models of purchasing, instead of wasting money and time like I did.

And I definitely recommend Room and Board– their mattress was a game-changer for me!
