made a guide for my pax display a while back on sf, it was the best display cabinet i could find for 1/4 and larger statues after wasting god knows how much money buying all sorts other furnitures that could barely fit a few statues.
Pasted below, hopefully can help you. I am looking to get another as this already got filled to the max now.
------------------
The best display is ikea's PAX, NOTHING comes close in term of flexibility, price, & space. It's also the ONLY display under $2000 that has a real 22" shelf depth (vs 17" max for all the others). It let you display statues the way you want (ie the avenger team stack), and the only display that will fit the optimus prime statue. It also has dust resistant sliding doors like the highend curios as oppose to besta open doors. Lastly it comes with 93+" height option, which will allow 31"+ per shelf height, that will fit most if not all CM and lsf statues as well.
I am currently building one using custom non-glare 99% uv-resistent acrylic panels designed for museum display, will post some details/photo once done in a week or two.
Should have gone this route long time ago, instead of wasting thousands of dollars buying those giant grandma's curio with little depth that can barely fit anything but takes up sooo much space.
Finally got around to take some photos, see the finished PAX. A few notes:
1) In the comparison photo, see the pax DWARFS the $1300 Macy's curio(which is a huge piece already, i use it as a dedicated lotr display now), and this is the smaller PAX...
2) Note how with the extra shelf depth i am able to display the riders facing front or to stack the conan/barbarian/leonidas, all are giant pieces which would taken significantly more precious shelf width in a regular 15" depth shelf. And it's the only shelf that fits optimus perfectly.
3) See next post for a quick guide to build your own as I did the research already, hopefully someone can benefit from it.

How to build your PAX (see previous post for photos)
1)
Select the correct PAX base (link:
https://www.ikea.com/us/en/catalog/products/S79894902/#/S19894900 ).
Use the drop down to select your width/height, you have 4 options: 59"x25"x79", 59"x25"x93", 78"x25"x79, 78"x25"x93". Do NOT select other options, as the internal shelf will be inappropriate, if you need even wider ones, buy 2x. And select your wood color.
2)
Select the shelf (link:
https://www.ikea.com/us/en/catalog/products/30215122/ )
You need at least 3 pack (for 6 shelves), select the correct width/color. Dont use the glass shelves, they too risky.
3)
Select the lighting(optional): (link:
https://www.ikea.com/us/en/catalog/products/50163848/ )
The best lighting for statue display are evenly distributed soft light in the 2000k to 5000k range, basically you shouldnt notice it's on. The WORST kind are those uneven glaring halogen spotlights used in most glass curios that destroy your statue aesthetic, they are great for glass plates & swaroski not giant polystone statues. Also LED is much preferred over the rest as it doesnt get hot and long lasting, having an oven above your statue for years is never a good thing.
That said, the ikea led strips linked are excellent, they are designed for PAX and fits across the entire shelf perfectly for even light distribution. Only downside is it's expensive at $35 per shelf. If you do decide to use the ikea led, you also need the wires that are not included, for 6x led strip, you need

4)
Order your custom display panels. (link:
https://www.professionalplastics.com/PLEXIGLASS-ACRYLICSHEET-EXTRUDED )
Wait until you receive your PAX, then take out 1 of its non-clear glass panel, measure the width/length/depth precisely. Then goto any one of the websites to order 6x clear acrylic panel of the exact same dimension (go with <0.062 tolerance which is the standard). I use professionalplastics.com, also checkout ebay or local stores. Dont get fancy, use standard clear acrylic or lexan.
Note: you can also use glass panels, however they are 2x as expensive due to shipping, weight twice as much, and less clear. The yellowing/scratch issue of acrylics are way overblown, i have kept acrylic fish tanks my whole life, never had any issues (and those have 300+ watts of simulated sunlight blasting at it 11 hrs a day).
5)
Install your PAX!
Follow the instructions, make sure it's secured to the wall! Dont try to win the darwin award for getting crushed by your own display shelf, those things are very tall and ikea quality..
Here's a video that i found very helpful with installing the sliding doors. Link:

POST YOUR PICTURES! 
NOTE: total cost for my pax 59"x25"x93" is ~$800
