Loft bed base expands from a King Single through to a King Size! 

Our expandable floor bed base is suitable for a 2m long King Single through to a King size bed! It can even accomodate any custom mattress size in between to suit your space, and if you ever change your mattress size, you won't need to buy a new base!

The bed base was initially designed with Tiny House lofts in mind, as it's as low as possible to allow as much headroom in your loft, but high enough to give enough ventilation to the bottom of your mattress. However, it turns out this bed base has also been very popular with those who want a Montessori Floor Bed Base that can be expanded as the child grows and wants a bigger bed, or for co sleeping. 

The reason why it's not advised to put a mattress directly onto the floor it that the bottom of your mattress doesn't get any air flow and moisture from the mattress gets trapped underneath and can lead to mould!

The bed comes in two parts and is assembled by screwing in the provided 4 screws with a phillips screwdriver.  By being in two parts it makes it easier to manoeuvre in small spaces, and a bit lighter than carrying it all in one long length. 


  • Bed base size from a 2m long NZ King Single to a NZ King Size Bed (a 2m long NZ Single can also fit with a small trim of the base exposed around the edge of the mattress. It would be approx. 15mm trim depending on the size of your mattress which would be mostly covered by the duvet). At the bases smallest size it's 950mm wide. 
  • Height is 36mm
  • Each half of the bed base weighs approx. 11kg
  • NZ Made with Naked Pine Ply 
  • Comes shipped in 2 separate boxes
  • 4 screws provided

Notes: You still need adequate ventilation to prevent any mould forming and if there is mould in the mattress already, you will need to get rid of it before putting on these slats or it will also get in the pine and continue to grow. Every bed will have a different pine grain, and won't be exactly like pictured. There may be some small gaps in the ply within the slats which doesn't effect the strength and won't be seen with a mattress on.

Tiny Home loft base.

Highly recommend. Very easy to assemble. The adjustable feature is very underrated as we have bought and sold a few bases before as our family needs change. With this design we would have been able to keep same bed for different bedding options. Also great to deal with. Thankyou.

Floor Bed Base

Exactly what we needed for our baby girl ! We wanted a floor bed for more security and freedom. And we decided to give her a king size mattress so your Floor Bed Base was our solution 😊 easy to build too so thanks a lot 🙏🏻

Great floor bed!

Such a great floor bed design! Makes sleeping much safer for our 8 month old, who is always trying to crawl off the bed. So good to have an adjustable base so that we can also use it as a toddler bed for him when he's older. Love your work!

Perfect toddler bed

Really impressed with this bed, and super easy to set up. My 3 year old loves her new 'big girl' bed.

Chiropractic Bed Base

This is a great product which is good for your posture. According to my chiropractor, the lower the base is to the floor, the more support you get when you are on the mattress and bed base. I have been suffering from lower back pain every time I am on the mattress. I researched a lot to find a suitable bed base, and this product completely solved my problem. It is easy to set up and has enough space for ventilation underneath, preventing moulds from forming under the mattress. This product is G! It definitely served my purposes. Even my chiropractor recommended me this product.
