Buying a new mattress can be a stressful endeavor. There are many factors which lead to this stress, including negotiating for a better price, shady salespeople, too many choices and worry that you will get stuck with the wrong mattress. With many stores and so much to choose from, it can be a bit overwhelming.
The first 30 days of life with your new mattress can be stressful on your body as well. A new mattress can have a break-in period that makes it feel different than the one you may have tried on the showroom floor, or be different than the one you read about online. The mattress can feel different than your last mattress, making it unfamiliar to your body and thus uncomfortable. It can also provide proper support while your old mattress had broken down and lost its ability to support your back properly, making the new bed cause some discomfort.
These factors are why most reputable mattress companies, such as Nest Bedding, allow a return privilege coupled with a break-in period. The break-in period, which is usually 30-60 days, gives the body ample time to adjust to a new support system and allow for any break-in of the mattress.
Not all mattress are made the same, and not all are subject to the same shipping. For example, a traditional memory foam mattress, such as Tempurpedic, can feel very stiff when new and soften up over time. The Bed In A Box Memory Foam Mattresses however come compressed in a box, effectively breaking them in already. They will feel the same on the showroom floor as they do out of the box.
A new Simmons, Sealy or Serta will also typically have a break-in period where they may feel firmer initially compared to the floor display. There are layers of foam above the coils which will soften up with use.
New organic latex mattresses will typically not have much of a change in the feel from when they are new. Latex is rubber, a very strong and resilient materials. There could be some settling in the surface of the mattress if it is made with wool quilting, typical of most organic mattresses. However, they will usually feel the same on the showroom floor as they do they day you get them and 5 years later.
If you have a new mattress and are experiencing some pain or discomfort, give your body a chance to get used to the new mattress before tossing in the towel. I cannot tell you how many customers over the years have called to express their initial displeasure only to find the bed is supportive and comfortable a week later.
