A bunkie board is a thin, firm panel that sits under a mattress in place of a box spring. For a twin bed it can add support to a slatted frame, a bunk or a sofa bed without adding height. This guide compares three twin bunkie boards from Amazon. We have not tested them, and their listings do not agree with each other on size, so read the size notes before you order.
Quick answer
A standard twin mattress is about 38 in by 75 in, and two of these three listings give that size in the title. The Bunkie Board Twin Size 10mm and the Bunkie Board 10MM Folding Spring Box both name 75 x 38 in, and the Folding Spring Box lists an item size of 75 in L x 38 in W x 0.39 in thick. The Imperius Foldable Box Spring is titled 60 x 30 in, which is 15 in shorter and 8 in narrower, so it is not a full-length twin board unless the listing shows an unfolded size that you confirm. Only the Imperius states a load figure, 120 kg.

The three boards in detail
Bunkie Board Twin Size 10mm, Anti-Slip Bed Slats
What it is. A twin bunkie board titled 75 x 38 in, with a 10 mm high-density core and a 0.4 in profile. It has anti-slip slats and weighs 11.48 lb. The listing says it works with metal frames, slatted frames, flat platform beds, bunk beds, sofa beds, RV beds and daybeds, with tool-free installation. The dimensions field reads 39 x 25.5 x 2 in and is labeled as package dimensions, so it describes the box, not the board.
Who it suits. Someone adding a thin, firm base to a slatted or bunk frame where height is tight.
- Pro: the title gives the full twin size, 75 x 38 in.
- Pro: a very low 0.4 in profile, so it adds almost no height.
- Pro: a long list of compatible frame types.
- Con: no weight limit is stated, which matters for a support board.
- Con: the 2 in figure in the dimensions field is for the package, so confirm the real thickness on the page.

Imperius Foldable Box Spring, Bunkie Board Twin (60×30)
What it is. A foldable wood bed support board in a log color, titled 60 x 30 in. The details show 0.18 in thick. Weight is given as 4.35 kg in one place and 11 lb in another, so the two do not match. It states a maximum weight recommendation of 120 kg and is meant to keep the mattress firm without a box spring’s bulk. A bullet gives 30 in long by 60 in wide, which reverses the order, so the orientation is unclear.
Who it suits. A smaller or shorter bed, or a case where you want a stated 120 kg rating and the 60 x 30 in size fits your frame.
- Pro: the only listing here with a stated maximum weight, 120 kg.
- Pro: foldable, with a very thin 0.18 in profile.
- Con: 60 x 30 in is 15 in shorter and 8 in narrower than the 75 x 38 in twin size.
- Con: weight is listed in two different values and the load is in kilograms only.

Bunkie Board 10MM Folding Spring Box, Twin Size 38×75
What it is. A folding twin board listed at 75 in L x 38 in W x 0.39 in thick. The listing describes a 10 mm medium density groove board inside a 600D Oxford cloth cover with silicone bumps against sliding, and a zipper so the cover can be taken off and washed. It is aimed at sofa beds and says the board is thick enough to support three adults, but gives no number. The material field reads vacuum plate, and no item weight is stated. Other fields on the page may show different numbers, so confirm the size before ordering.
Who it suits. A sofa bed that sags, where a washable cover is useful.
- Pro: zippered cover that can be washed.
- Pro: silicone bumps are described as preventing sliding.
- Pro: size matches a twin, 75 x 38 in.
- Con: no weight limit, only a claim about three adults.
- Con: the material field says vacuum plate, while the bullets say groove board, so the construction is unclear.

Buying checklist
- Measure your frame and mattress. A twin is about 38 in by 75 in.
- Compare the title size with the dimension fields, and treat package dimensions as the box, not the board.
- Check thickness against the clearance in your frame.
- Look for a stated load. Only the Imperius gives one, 120 kg.
- Check the frame type: slats, platform, bunk or sofa bed.
- Check the weight and units, because values are listed in both kilograms and pounds.
- Look for a washable cover if you want one.
Frequently asked questions
What size is a twin bunkie board?
A twin mattress is about 38 in by 75 in. The Bunkie Board Twin Size 10mm title and the Folding Spring Box title both give that size, and the Folding Spring Box lists 75 in L x 38 in W. The Imperius is titled 60 x 30 in, which is smaller. Measure your frame and check each page.
Which has a stated weight limit?
Only the Imperius lists one, a maximum weight recommendation of 120 kg. The Folding Spring Box says it supports three adults without a number, and the Bunkie Board Twin Size 10mm states none. We have not tested any of them, so verify before relying on them.
Will it work on a bunk bed or slatted frame?

Can I wash it?
The Folding Spring Box listing describes a zippered Oxford cloth cover with a removable board so you can wash the cover. The other two listings do not mention a washable cover, so assume wiping only and check the care notes on their pages.
Closing note
Because these three listings disagree with each other, the safest step is to measure your frame, then confirm size, thickness and load on the product page. Details can change, so check them before you buy.
