This is how I made a waterbed frame from IKEA KALLAX

This waterbed frame hack is very similar to the “A
full-sized bed built from KALLAX shelves + a DIY headboard
“,
but was build to support a full-sized waterbed.

This construction must be much more stable to support
approximately 400 kg, but on the other hand, requires no
ventilation for the mattress.

For obvious reasons, I decided to use the KALLAX shelves. They have a
comfortable height for getting in and out of bed and can be easily
combined due to the variety of modules.

Material list for the waterbed frame: IKEA

    shelves 2 x 1 (77 x 42 cm)
  • 1 KALLAX shelves 4 x 1 (147 x 42 cm)

  • 2 medium-density fibreboard (MDF) (200 x 75 cm)
  • 1 oriented strand board (OSB)(20mm) (158 x 69 cm)
  • 8 planed timber (50x50mm) (35 cm)
  • 4 planed timber (5x5cm) (69 cm)
  • Impact sound insulation (3,5 m²)
  • Laminate (3,5 m²)
  • Aluminum equal angle profile (5,5 m)
  • LED stripe (5 m)

How I made the KALLAX waterbed frame

This is the first sketch I did when I had the idea for this
waterbed frame. It did not include the four wooden boards to
support the weight.

But, I was not sure if the KALLAX shelves where strong enough to
carry a waterbed. So I placed four wooden boards between the
shelves.

I used some L-brackets and
steel braces to connect the
shelves

To support the main weight, I used eight legs, that held up an
Oriented Strand Board, that exactly fitted between the shelves

The waterbed base was finished. Time to do something for the
optics. I bought two MDF boards that when combined were a bit
larger than the base.

The reason, I had bought two boards and not one was a single
board 150×200 cm would not fit into my car.

I was not sure if I would need it, as no one ever would walk on
the laminate boards. But I had enough impact sound insulation left
over from the last conversion so I had it installed under the
laminate boards.

The laminate did not have to be laid floating and so I screwed
it on to the MDF board.

I sawed the aluminum profile, mitered and glued it with hot glue
on to the MDF board.

The aluminum profile is 4 x 4 cm, which left enough room, to
stick an adhesive-backed LED
strip
on the inner vertical side of the profile.

Well, I thought this is it and the work is done…

…but after looking at the bed for a while I thought a
headboard was missing. Not much. Just a place to drop a book or
smartphone or something like that

Material list for the waterbed headboard: IKEA

  • 2 MOSSLANDA picture ledge (115 cm)
  • 1 MOSSLANDA picture ledge (55 cm)

Non-IKEA

I cut a short MOSSLANDA picture ledge in half and screwed the
four ledges on the chipboard. The lower ledge was on the same
height as the bed and the upper ledge at a height so that a book or
tablet would not accidentally drop over the edge.

Since the chipboard was cut to the correct size, I had to

iron on the banding
.

The headboard was just placed between the wall and the bed and
not fixed to either of it. The last step was to glue the
quarter round strip moulding
to the bed.

I did not do any calculation of how much weight this bed might
carry, but I can tell you that it is now supporting my 140×200 cm
waterbed for more than a year.
