What should I consider when combining two separate mattresses into one bed?
When combining two separate mattresses into one bed, you should pay particular attention to equal sizes (length, width and height), avoiding a gap between the mattresses, and choosing the right connection method. A good mattress connector or topper will help you create a seamless transition so you can sleep comfortably without suffering from a gap in the middle.
Why do people choose two separate mattresses in one bed?
Two separate mattresses in one bed offer individual sleeping comfort, especially for couples with different sleeping preferences. One partner may prefer a firm mattress, while the other prefers a soft one.
A big advantage is motion isolation. When your partner moves a lot at night, you feel it less in your own mattress. This ensures less sleep disruption and a better night's sleep for both.
Practically speaking, it is also convenient for transportation and maintenance. Two separate mattresses are easier to get up the stairs than one large mattress. Also, you can turn them over separately or replace them when needed.
For people with different body weights, this system also works well. A heavier person often needs more support than a lighter partner, and with two mattresses, you can accommodate that perfectly.
What sizes should you check when combining mattresses?
The length of both mattresses must be exactly the same, or you will get an uneven bed. Measure both mattresses and make sure they are exactly the same length, usually 200 or 210 centimeters.
Height is also important. Mattresses with different thicknesses make for an uncomfortable transition. The difference should be no more than 2 centimeters, but preferably no difference at all.
Measure your bed frame or box spring carefully. Two 80-centimeter wide mattresses fit perfectly into a 160-centimeter bed frame. For a 180-centimeter wide bed, you need two 90-centimeter mattresses.
| Bed frame width | Mattress 1 | Mattress 2 | Total |
|---|---|---|---|
| 160 cm | 80 cm | 80 cm | 160 cm |
| 180 cm | 90 cm | 90 cm | 180 cm |
| 200 cm | 100 cm | 100 cm | 200 cm |
How do you prevent a gap between mattresses?
A mattress connector is the most effective solution against a gap. This is a foam strip that you place between the mattresses that perfectly fills the space.
A topper over both mattresses also works well. Choose a topper that is slightly wider than your bed so that it falls snugly around the mattresses. This creates one smooth surface with no perceptible transition.
Coupling foam is another option. You press this soft foam between mattresses and it conforms to their shape. It is cheaper than a mattress connector, but sometimes less durable.
Also, make sure your mattresses are snug against each other. Check regularly to make sure they haven't slid apart, especially on a box spring where the mattresses can move around a bit.
What are the best methods for connecting two mattresses?
Mattress straps are a popular choice. These adjustable straps go under the mattresses and hold both mattresses firmly together. They are easy to install and adjust. At Bröring, we often use connecting zippers. These allow you to easily connect two separate mattresses into one. This prevents the mattresses from sliding apart and eliminates the annoying seam in the middle. At the same time, flexibility is maintained: you can always unzip the mattresses to use them separately, turn them, or clean them.
Mattress clips clip onto the sides of both mattresses. They are discreet and do not interfere with sleeping comfort. However, you do need to check if your mattresses are suitable for clips.
A mattress connector with Velcro strips works well for lighter mattresses. You stick the Velcro strips on both mattresses and connect them securely.
For a luxury solution, you can opt for a special mattress topper that covers both mattresses. This gives the most comfort, but is also the most expensive option.
| Method | Advantages | Cons |
|---|---|---|
| Mattress Straps | Sturdy, adjustable, inexpensive | Visible, can shift |
| Mattress Clips | Discreet, easy to use | Not suitable for all mattresses |
| Topper | Best comfort, luxurious appearance | Most expensive, additional maintenance |
Important points to remember when combining mattresses
Always ensure identical dimensions in length and height. This is the basis for a well-functioning combination. Double measure everything before you start.
Test out different connection methods. What works for one person may not necessarily work for you. Some people feel mattress straps; others don't.
Consider the lifespan of both mattresses. If one mattress wears out sooner, you may need to replace both to keep the sizes the same.
Don't forget maintenance. Two separate mattresses require more attention than one mattress. Check regularly to make sure they are still well connected and that no gap has developed.
When in doubt about the best solution for your situation, you can always ask for advice. We have more than 100 years of experience in sleep comfort and are happy to help you find the perfect sleeping solution, whether it's combining mattresses or choosing a completely new bed system.

Top service!
About four years ago, I bought a beautiful bed at Broring, Gelderlandplein. Stephan helped me.
I lived nearby.
Now that I've moved in with my partner and live in Bloemendaal, I was having problems with the bed's controls.
My boyfriend contacted Broring about this many times by phone and email. When that didn't work, Stephan came by to fix it!
We thought that was great service because I no longer live in Buitenveldert, so I'm not next door!
I was also helped in the store by a somewhat older person, blond/gray hair, glasses, who was always very friendly!
The quality of the items, including sheets, towels, etc. in the store is also very good.
