I have some particleboard bookcases and CD shelving that either tend to tip or lean away from the wall, or have shelves that sag, or both. Whether you buy these at IKEA or not, sometimes your best bet is to pull them slightly away from the wall (by a couple of inches, say) and then gently tip them against the wall, so they rest, slightly tilted but stable. And then prop up any sagging shelves with small pieces of wood, etc.
Why not put shims under the front of the bookcases so they stand up straight? Shims are 10 for $2 at any home improvement store.
Presumably you need a different curve on the knife to perform a bris.
One thing that I thoroughly recommend from Ikea is their kitchens. I’m just in the finishing stages of a DIY rip-everything-out-and-start-again kitchen renovation, and the whole thing will come in at comfortably under £7,000, including most appliances (reusing fridge/freezer and dishwasher), and including getting tradesmen in to rewire the kitchen, move plumbing, lay underfloor heating and tile the floor.
Getting a big kitchen company in to do it would have cost probably three times as much, and I’m really happy with the look and quality.
I have many IKEA purchases that have served me well. The only one that is a problem for me is my own fault - the hutch part of my TV cabinet is supposed to have a back to it to keep it rigid, but I have removed it to let cables through, and it has weakened it. I need to locate a perfectly sized cross bar support…
If the particle board was hot enough to burn you, wouldn’t it have burned through the box it was in. too? Seems easy enough to spot before you buy.
