All mattresses will eventually soften, sag or get an imprint from where you’ve been sleeping. The good news is that latex does it at half the rate of a conventional material. The normal compression in a traditional mattress is an inch and a half to two inches. Your Spindle is warrantied against impressions greater than 3/4″. That’s a “yuge” difference.

Here’s the transcript:

A common question we get is will a natural latex mattress soften or sag? And if you’ve been doing research online, you’ve seen people showing off a 30-year-old mattress. This is more the exception than the rule. Latex can last beyond 10 years sometimes, but there are a lot of other factors that affect the performance and durability of a latex mattress.

One factor is height and weight. For example, I’m 6’4″, 230 pounds, and my wife s 5’10” and 130. Her side of the mattress will last longer than my side. My body density is higher, so I put more stress on the mattress than she does, so I’ll see more softening and more compression on my side of the bed. Now, keep in mind that any mattress, no matter how well it is made, won’t look the same or be as smooth or flat as the day you got it. Nothing lasts forever, even the best materials.

All materials soften and sag over time. The advantage is latex does it at half the rate of a conventional material. The normal compression in a traditional mattress is an inch and a half to two inches. That’s big! With our mattress and other latex mattresses, you should see about 3/4 of an inch in 10 years, and latex will soften 15% over a 10 year period, whereas conventional materials can soften 30% or more. The softening and compression will occur where heat, moisture, and weight are applied. This is where you sleep, so the mattress will feel firmer where you don’t.

Please keep in mind within the first year the wool will settle and compress. This will make the cover look a little looser and baggier. The great thing is our design has a lot of advantages in preserving or extending the life of your mattress. First is you can rotate the layers inside of the mattress, like rotating the tires on your car, to even the wear on the latex. For example, with our medium mattress, simply switch the position of the two medium layers. So we’ll take the top layer and remove it, and remove the middle layer. Now the top layer will become the middle and the middle will become the top. Second, if the mattress is softened or compressed beyond your liking, but inside the normal and expected range, you can buy a new layer to refresh your mattress, rather than replacing the whole mattress. With our Comfort Life program, owners of a Spindle may purchase the components at 30% off.

Finally, to make the mattress last, we have a few tips. First, make sure to get a good mattress protector. We have a list on our site recommending different types. We recommend ones like this, which have a cotton terry face and backed with a polyurethane membrane for waterproof protection. Second is supporting your mattress properly. A lot of early compression or softening that we hear about is related to improperly supported mattresses. What works well for an inner-spring isn’t the case for a latex mattress. Check out our specs on our site to make sure that you properly support it, and remember to be careful. Not all frames are built to support the weight and flexibility of latex. Even the expensive ones don’t always work, so if you have any questions about support, comfort, durability of our latex mattress, feel free to give us a call, send us an email. We’re happy to help.
