How Many Mattresses Should a 100-Room Hotel Keep in Stock?

A new procurement manager almost always starts with the same assumption: one mattress per bed, done. In practice, a well-run hotel carries spare stock — and getting that number wrong in either direction costs money, either in idle inventory or in emergency same-week orders at a worse price.

Start with your replacement cycle, not your room count

A hotel-grade spring mattress under normal commercial use lasts roughly 7 to 10 years before support noticeably degrades, assuming daily turnover and standard housekeeping. That means in any given year, roughly 10–15% of a property's total mattress stock is due for replacement — not all at once, but on a rolling basis.

For a 100-room property (assume 1.5 beds/room average = 150 mattresses):

• Annual replacement need: 15–22 mattresses/year on a rolling basis
• Damage/complaint buffer: 2–3% of total stock held as spares (3–5 mattresses) for guest complaints, stains, or accidental damage that can't wait for a scheduled reorder
• Renovation reserve: if a wing renovation is planned within 18 months, order that wing's full requirement in the same purchase order as your annual replacement batch — bulk pricing improves meaningfully above 30–40 units

Why "order when it wears out" is the expensive way

Reactive ordering — waiting until housekeeping flags a specific mattress — means small, frequent purchase orders. Bulk manufacturers price per unit lower as order size increases, and GST-compliant B2B billing is simpler to reconcile as fewer, larger invoices rather than a dozen small ones through the year. Most properties that switch to a planned annual batch order see a meaningful per-unit cost drop purely from volume, separate from any negotiation.

A simple planning table

Property size	Annual replacement (rolling)	Recommended spare buffer
50 rooms (~75 beds)	8–11 mattresses	2–3
100 rooms (~150 beds)	15–22 mattresses	3–5
200 rooms (~300 beds)	30–45 mattresses	6–9

What to check before placing the batch order

• Warranty terms — hotel-grade ranges typically carry 5 to 12-year manufacturing warranties depending on the range; confirm it in writing on the quote, not just verbally
• HSN code and GST rate — mattresses fall under HSN 9404 at 18% GST; make sure the quote reflects this so there's no surprise at invoicing
• Delivery scheduling — a manufacturer that can stagger delivery across a renovation timeline avoids you having to warehouse 40 mattresses on-site for weeks

Planning stock around a replacement cycle rather than reacting to individual wear-outs is the single biggest lever hotel procurement teams have on mattress cost — before any negotiation on price per unit even starts.
