I find it odd that the Eket is being lauded as sturdier over the Kallax or older Expedit series. The latter two can hold twice the weight per shelf as the Eket can which is only 15 lbs per shelf the others are 29 lbs per shelf. At 50 lps approximately per shelf , 15 lbs of max load is pushing it on the Eket. The dimensions are not the only supplied data of the on line description.
I have an eight cube Expedit , ( 2, 4 cube units ) loaded with just with my Blue note and rare import lps, and unlike a unit in a showroom that is put together without load or fastening to a wall, by some kid,
these units are surprisingly strong and sturdy when put together and fastened properly. Probably a good reason why they were and are so popular. I have the majority of my other 8000 albums in shelving I made decades ago out of 3/4 Russian ply ( before it was as absurdly priced) , dado and glued in a dry basement room . Even given that overkill , I have no qualms or worries storing some of my most irreplaceable gems in the Expedit in the living room. I made a couple wooden crates that I swap out every couple weeks or so from the basement storage to keep rotation with less room taken up in the livingroom. I do like the look of the Eket on those wood bases though, but I wouldn't load them as heavily as the Expedit and feel as sure of its 15 lb per shelf rating vs the 29 lb rating of the Kallax and Expedit. I think either is a good economic choice when used properly and within their limits. A little dab of carpenters glue on those dowel pins is what many do to "stiffen them up" and either a back or fastened to the wall ( especially if you have kids or grandkids visiting) . What ever works , and its for keeping vinyl spinning is great in my book...................
