This is a great question. We reached out to the manufacturer for guidance, and they gave us very detailed information about installation and the weight limits. Please review below and if you have any questions let us know! You can also contact MASH studios at 310.313.4700.
The 3X Wall-Mounted Shelf and Wall-Mounted Desk both mount to their respective wall(s) using snap-toggle anchors, which are rated for 100 lbs each.
The 3X Shelf uses a total of (4) anchors, while the desk uses (6). The holes designed to accept the anchors are evenly spaced throughout the back panels of each piece, to distribute any weight applied to each piece evenly.
While each snap anchor is rated for 100 lbs, this does not take into account the weight of the pieces their selves, which is between approximately 50 and 60 lbs.
While we don't have a formal weight rating for each piece, one could estimate that the weight rating for each anchor, multiplied by how any anchors are provided per product, minus the weight of the shelf or desk, respectively, would bring you an approximate weight load that each piece could handle.
In our experience, most computer monitors can rest on the wall-mounted desk, and household items on top of and within the 3X and Desk without issue. While a projected weight rating may be accurate if the weight is applied evenly and gently on these pieces, of course a sudden or very acute
application of said weight could cause one of these pieces to bow, crack, or fail completely.
The desk and shelf are designed for residential use, so commercial use, such as storing extremely heavy items is discouraged and not the warrantied, intended use.
The toggle anchors are included as these are the designed, recommended anchors with which one should and can mount these pieces without the use of studs, and therefore gives on the most latitude as far as where one can place the piece on the wall horizontally and vertically.
You can, if you wish, use lag bolts or other aftermarket heavier-duty mounting bolts, especially if intending to mount to studs, through the pre-configured holes in the pieces, but drilling your own holes in the panels would void the warranty on either piece.
The spacing of the pre-configured holes in these pieces' panels are not measured at distances that match evenly to more than one set of studs per piece, so even if one were to use lag bolts to match to one stud through one set of vertically aligned panel holes, the remaining hole(s) would have
to mount to the drywall using the toggle anchors.
We have not experienced any issues with toggle anchor failure, however the variations in some customer's drywall strength, or how effectively the toggle instructions are followed, could cause the actual drywall to give way, rather than the pieces or anchors their selves.
