What should a first-time buyer decide first?

Decide your constraints in this order: space and carrying route, total-cost boundary, maintenance willingness, then delivery terms in writing. That is the honest answer for almost every first-time buyer, and this page is not product advice — no category, brand or model follows from it. What follows is a worksheet you can complete with a tape measure, a note and one email to a seller, so that whatever you eventually compare, you compare it on numbers you already trust.

The decision order worksheet

Copy these four rows onto paper. Each has two parts: what to write down, and what to do next if you cannot fill it in. A row is only "done" when it holds something specific — a measurement, a number, a named routine, or a written policy line.

#	Row	What to write down	If it is missing, the next step is
1	Space, carrying and route	The storage spot (position + clear dimensions), the tightest door/turn/stair on the route, and the unboxing area — all as measured numbers	Measure before browsing; until then, form and weight comparisons describe items that may not fit your home
2	Total-cost boundary	One all-in ceiling: product + delivery + taxes + first care supplies, with uncertain lines marked	Set the ceiling before comparing; a missing ceiling lets every unknown cost count as zero
3	Maintenance willingness	The routine you will actually repeat on an ordinary evening — wash, dry, store — written as steps, not intentions	Decide the routine before choosing a material; the material sets how demanding that routine tends to be, not whether it exists
4	Delivery terms in writing	The seller's stated packaging, labeling, delivery and returns terms for your address, saved with a date	Ask the seller in writing and pause comparing until the answer arrives — delivery terms can make any purchase impossible

Notice what is deliberately absent: no product preference row, no "which model" column. Those decisions come after the worksheet, not before it — and they get much shorter once the four rows hold real values.

Which row is blocking your browsing

You do not need to resolve all four before starting. Find the first condition below that is true for you — that is your blocker, and it names itself:

• You cannot measure your space yet (no named storage spot or unmeasured route) → your blocker is space. Nothing else is comparable until the tape measure has spoken. If you want help turning the measurements into a form direction, the space check on our companion site does that in five questions.
• You cannot write a single total-cost ceiling → your blocker is budget. Until one number exists, "which one do I like" quietly becomes "spend whatever it costs."
• You cannot honestly commit to a care routine → your blocker is material. Material choice is really a choice about the upkeep you will sustain; commit to the routine first, then pick the material that fits it.
• You cannot get delivery and returns terms in writing → pause the comparison entirely. This one is not a dimension to optimize; it is a gate. Any seller who will not state terms for your address has answered a more important question than any spec row.

One blocker, settled, is enough to restart browsing. Two blockers settled is a luxury. The point is never to finish the worksheet perfectly — it is to stop building comparisons on top of blanks.

Why the order is protecting effort, not judging you

The order exists so that no one spends three evenings of careful product comparison on top of a condition that could cancel the purchase. Resolving the row that can say "no" first means every later choice only has to answer "which." That is all the priority means — it is not a verdict on your apartment, your budget or your abilities, and no row on the worksheet asks you to prove anything to anyone but yourself.

What this page is not

It is not a product selector. Completing the worksheet does not output a model, a brand or a price — it outputs four confirmed conditions. It is also not a one-time ritual: a row can reopen (a move, a budget change, a new seller), and the right response is to refill that row, not to restart everything.

This page versus the path check

You can finish this worksheet entirely by hand — that is the point of it. The path check does a different job with the same inputs: it asks six questions, applies the priority order above mechanically, and hands you one named next step with the matching checklist. Use the worksheet when you want to see your own conditions on paper; use the tool when you want the order decided for you and a result you can act on in the next five minutes. Most people do the worksheet first, then let the tool confirm what they already suspect.

However you get there, the exit condition is the same: four rows filled in, no blanks pretending to be answers, and only then the first product page opened.
