The most expensive furniture mistake isn't the wrong color. It's the piece that doesn't fit. A sofa that looks perfect in the showroom and then eats the only walkway to your kitchen. A sectional that swallows the room instead of anchoring it. By the time it's delivered, the return window is a fight and the restocking fee stings. The fix is boring and free: plan a room layout to scale before you spend a dollar.
That's exactly what we built the Trig Studio to do. It's a free online room planner — set your room's exact dimensions, drag in real pieces at their verified width, depth, and height, and arrange everything to scale before anything ships. No guesswork. No painter's tape on the floor at 11pm. Here's how it works, start to finish.
Most of us shop one piece at a time. You fall for a chair, you buy the chair, and only later do you discover it crowds the coffee table or blocks a door swing. Furniture is a system. A room works when the pieces relate to each other and to the empty space around them — and empty space is the part people forget to measure.
Designers think in clearances, not just footprints. Roughly 30 to 36 inches for a main walkway. About 14 to 18 inches between a sofa and a coffee table. A few feet of breathing room so a sectional reads as comfortable instead of cramped. You can't see any of that from a product photo. You can see it instantly when the pieces are drawn to scale on your actual floor plan.
There's a money angle too. We work on a request-a-quote model — no public checkout — which means planning happens before pricing gets locked in. Plan first, then ask. You never commit to a layout you haven't seen at real size.
The whole thing runs in your browser. Most people get a usable plan in well under an hour.
Start by entering your room's width and depth in feet. Not a rough guess — the real numbers. The planner lays out a 1-foot grid and shows live square footage as you type. If your space isn't a clean rectangle, you can carve it: drag the walls, notch out a fireplace bump-out, build an L-shape or a U. Measure twice here. Everything downstream depends on this being honest.
This is the part that makes it trustworthy. The furniture in the Studio isn't generic clip-art — each piece carries its verified width, depth, and height, pulled from the manufacturer's own spec, not a number we made up. So when you drop an American Leather sofa onto your floor, it occupies the exact footprint it'll occupy in your living room. Search by name, filter by brand or category, and pull pieces straight from the lines we carry. (Want to browse first? The full catalog lives on our shop page.)
Now play. Snap a sofa flush to a wall. Slide the coffee table until the gap feels right. Drop in a sectional and watch whether it anchors the room or runs you out of it. Check the path from the front door to the kitchen — does a 32-inch walkway survive once the lounge chair is in? Rotate pieces, nudge them an inch, and the plan updates live. This is where you catch the mistake while it's still free to fix: the console that's three inches too long, the bed that crowds the closet door.
When the layout feels right, export a clean spec sheet — every piece, its real dimensions, a tidy bill of materials — or copy a share link to send to your partner, your designer, or us. One link, the whole room.
A finished layout is the start of a conversation, not the end of one. Send us the plan and we'll confirm the real-world stuff a planner can't: current pricing, lead times, and what's actually in stock versus what's a special order. Because we don't run a public checkout, nothing is locked until you've seen it priced — you're never committing blind.
If you'd rather sit with the pieces before you plan, come see them. Our showroom at 1053 E. Whitaker Mill Rd in Raleigh is open Tuesday through Saturday, and the Studio is a great way to prep before you visit — show up knowing your dimensions and your shortlist, and we'll help you close the gaps. Hours and directions are on our visit page.
And if you're an interior designer, the Studio doubles as a client tool. Build the room to scale, drop in real pieces, export a spec sheet your client can actually read, and order the whole project through one point of contact. More on that in our trade program — and in our guide to how the trade program works for designers.
The thread through all of it is the same: when you plan a room layout to scale with verified dimensions, the furniture fits the first time. That's the whole point.
Yes. The planner is free to use, no account gymnastics required. Set your dimensions, build your room, export your spec sheet. Pricing only comes into it when you send us the plan and ask for a quote.
Every piece in the Studio carries verified width, depth, and height from the manufacturer's spec — not estimates. That's the entire reason the to-scale planning works. If the numbers were soft, the layout would lie to you.
Get as close as you can — your plan is only as good as your measurements. If you're unsure how to measure for a specific piece, our guide on how to measure for a sofa walks through it, and you can always bring your numbers by the showroom and we'll sanity-check them with you.
