To get a good night’s sleep, besides a good memory foam mattress, latex mattress, and appropriate sleep position, you need a solid platform bed at home. These specially designed bed types don’t need box springs or bunkie boards.

However, what type of wood is best for bed slats? How can you calculate the slats? Do you know how to decide the number of slats based on their width? This post will bring you a durable and robust bed construction. Let’s find out the useful information below.

Calculate the Wood Slats

In this section, you know how to calculate slats for different standard beds for mattress sizes like twin size, full size, king size, and queen size.

The Spacing of Slats

In order to allow air circulation under the mattress and provide full bed support, you should place the stats not more than 2.5 inches apart. Note that the major mattress manufacturers will have a warranty policy with design requirements for the platform bed and slat spacing, you may need to adjust the space smaller than 2.5” to suit the type of mattress you use.

The Dimensions of Slats

Based on the slat width and standard slat spacing of less than 2.5”, you can calculate the number of slats to use. Typically, you make a slat with 1×3 lumber (2.5” wide) or 1×4 lumber (3.5” wide). These slats often have a thickness of about 3/4”. Now calculating and measuring the slats are easy to do.

For the 80” long queen and king size bed, you need around 17 slats of 1×3 and 14 slats of 1×4 if you have a slat at each end of the mattress.

For the 75” long twin and full-size bed, you need around 16 slats of 1×3 and 13 slats of 1×4.

After making the slat systems with your size of the bed, it’s easy to assemble the slat platform bed.

The Support for Bed Center

With a width of between 38” and 76”, all bed kinds need central support to prevent slack in the middle for better weight distribution. You should add rigid center support that runs from head to foot of the beds with slats. With this support, the slats extending less than their length should increase the strength of your wood slat platform bed. If you want a solid wood bed, you should choose stiff wood for your slats.

As a result, the hard bars and central support will give you a strong mattress foundation for preventing sagging and increasing longevity over time.

Now let’s talk about the best wood for your bed support slats.

Best Wood to Use for Bed Slats

Some users choose standard lumber available from a local timber workshop or home center. These woods are often inexpensive and soft for bed construction, so they use 1 x 4s to strengthen the bed frames. However, there are many good quality and durable wood materials to make bed slats. The properties of good wooden slats for a standard platform bed are flexural strength and rigidity.  Moreover, you should remember to buy straight, flat boards that are dried to prevent warping, and without knots that cause weaknesses. Check out some excellent types of these woods here.
