Things to Consider

However, before you part with your money, why not take a few minutes to look at our brief but extremely informative buying guide below? This is where we take a little time to elaborate on those features we mentioned above, explaining in a bit more detail why we consider them the most important elements you should be looking at here. Then, with this guide alongside our detailed reviews, you should be in a perfect position to select the right type of bunkie board which will satisfy your exact sleeping requirements.

What are the advantages of using a bunkie board, and what can you use instead?

5 Sturdiest Bunkie Boards to Prolong the Life of Your MattressIf you aren’t ready to purchase a bunkie board just yet or aren’t too sure about them overall, some people do instead used pieces of boards cut and fitted by themselves to achieve a similar effect. However, a proper bunkie board has many advantages, including:

  • Reinforcing your bed’s overall structure and sleeping surface
  • Increasing the life of your mattress
  • Encouraging your body to develop the correct spinal alignment
  • Improving your sleep in general

Features to consider before you buy a bunkie board

We believe there are a couple of essential elements that you should always look out for before you consider purchasing a bunkie board. These include the board and cover materials, the height of the board, the range of sizes available, the durability offered, its ease of assembly, and last but not least, its cost.

Board and cover materials

The materials of your board may be a personal preference, and some can offer two types in its makeup. We’ve reviewed the most two common types of board material here in that of metal and wood board choices, with the Zinus Deepak offering a combination of the two.

In addition to the board type, you may notice that some bunkie boards are also finished with a covering. This is usually a specific type of fabric which just offers a more visually benefit and perhaps a little more comfort than bare wood or metal surfaces, for example.

Bunkie board height

Bunkie boards should not be extremely high in construction as their sole purpose is to offer a good level of support, not increase your bed’s overall height! For this reason, you’ll find that most of the bunkies you come across offer a height of around one inch to one and a half inches as standard.

All the boards reviewed here range from one inch to 1.6 inches in total, and we recommend ensuring your chosen model isn’t any higher than this.

Available sizes

When selecting your ideal bunkie board, you need to ensure that the chosen size works to the measurement of your bed base. The best way to do this is by removing the mattress from the bed and measuring both the length and the width of your bed surface.

We have made sure to include those boards which offer a good range of sizes here, and most models will cover Full, Twin, King and Queen as standard.

However, we do note that you should also account for any fabric or padding here in your measurements, especially if you intend on adding such additionals to your bed later on. If you have a little extra clearance, you can indeed pad your bunkie board up as appropriate.

Whatever size you end up choosing, you will most certainly need it to be big enough in its surface area to completely cover the slats beneath it.


Many people will tell you that a bunkie board preserves the life of their mattress as it keeps it from sagging. However, this will only work if the bunkie board itself works to offer such durability, therefore meaning it will last you for a good couple of years at least.

The best way to derive whether your board offers full durability is to read the product details in full, whereby it should mention how durable the board is. All these boards have been chosen for their high durability levels. However, we also think it’s a good idea to take a look at the level of warranty offered here as this may give you an additional sense of the company’s confidence in the longevity of their products.

Two great examples here are the Zinus Deepak and the Zinus Gulzar, which both offer a fabulous five-year limited warranty on their bunky boards.


5 Sturdiest Bunkie Boards to Prolong the Life of Your MattressA good quality bunkie board should not cost the earth. After all, it is not offering to replace your bed base, nor your mattress. It is merely to provide additional support in between. Therefore, you should ideally be looking to spend under the $100 mark here.

The Zinus Gulzar is our budget pick here and perfectly highlights how easy it is to get a thoroughly useful highly rated bunky board for a smaller and lower cost of around the $50 mark.

With the highest model on the list here ever so slightly tipping the $100 mark, we’re sure you’ll find these prices perfectly adequate.

How to install a bunkie board?

The great thing about bunkie boards is their minimal installation requirements! With almost nothing for you to piece together, for many it’s merely a case of taking the board from out of the box or packaging you receive it in and then laying it over your bed’s foundations, placing the mattress straight down over the top!

The Wolf Split Bunkie Board comes in two separate pieces whereby you simply piece them together to complete the board, whereas the Zinus Gulzar allows a quick lock construction to make assembly as straight forward as possible, with the Signature Sleep Ultra Steel Bunkie Board taking a mere four easy steps to fully assemble!


Some bunkie board manufacturers may have a weight limit with their specific models. However, bunkie boards in general, are said to be able to cope with heavier weights as opposed to box spring choices. This is because they work hard to equally distribute your body weight as you lie upon them. We recommend checking with the manufacturer’s instructions beforehand as opposed to what weight your chosen model can accommodate. For example, the Wolf Split Bunkie Board specifically states it has a weight limit of 100 pounds for this board type.

The whole concept of a bunkie board is to support almost any bed frame that needs an additional layer of support between the frame and the mattress itself. They were also initially better at offering a more stronger support foundation to those with the thinner of mattress styles. However, these days, they are aimed more towards those with platforms, foundation, and indeed bunk beds. Once again, always be sure to double-check the manufacturer’s instruction with regards as to what bed types your particular model is suitable for.

Once again, bunkie boards work well with a wide variety of mattresses types. However, the mattress types that really benefit from these fantastic additions are those foam, memory, and latex types. This is merely because they are created to support that extra weight that such mattresses carry with them.

Our Verdict

We hope by now, you have a better idea of what a bunkie board can do for you, alongside what factors of these fantastic features will apply the most to your individual needs.

Our top choice here is the Zinus Deepak. What we like most here is the combination of both a metal and wood board material combined together with non-slip tape that is featured on the wooden slats.

Second place goes to the Zinus Gulzar, which we believe offers an astonishing number of features and benefits but with one of the lowest of price tags attached! In third place, we’ve selected the Signature Sleep Ultra Steel Bunkie Board because we love how well this works with all mattress types but especially those foam and memory mattresses, which so many of us have these days.

Overall, we believe that all the five bunkie boards reviewed here are thoroughly effective at offering an all-around complete sleeping solution, ensuring a better quality of bed and indeed improved sleeping surface for a good number of years to come.
