4.6 · 22,000 reviews
Editor score8.1/10
Best for: Anyone with a real bed-bug history or a severe dust-mite allergy who wants lab-certified, warrantied assurance rather than a value-tier seal.
Certification
Lab-certified bed-bug proof
Style
6-sided zippered encasement
Waterproofing
100% waterproof
The serious encasement — lab-certified bed-bug-and-dust-mite proof with a 10-year warranty, for when 'probably sealed' isn't good enough.
This is the encasement you buy after you've actually had bed bugs. It's a six-sided zippered shell that's 100% waterproof and lab-certified against both bed bugs and dust mites, backed by a 10-year warranty most rivals don't touch. The tradeoffs are the encasement tradeoffs, amplified by the price: at ~$37 it costs more than the value seals, it feels firmer than a comfort pad, and fitting it is a two-person job.

Should you buy it?
What we like
- Lab-certified against both bed bugs and dust mites — independent testing behind the claim, not just a marketing label
- 100% waterproof across all six sides, so the entire mattress is sealed against liquid, not just the top
- 10-year warranty — far longer than value encasements, signalling confidence in the zipper and seams over the long haul
- Full zippered encasement with a robust closure designed so bugs cannot pass through or escape
- 22,000 reviews at 4.6 stars — the highest rating among the encasements here, from buyers with the most demanding needs
What to know before buying
- At ~$37 it's the priciest encasement on this list — you pay a premium over the Linenspa for the certification and warranty
- Full six-sided encasement feels firmer and less breathable than a plush fitted protector — it's a barrier, not a comfort layer
- Installation requires lifting and zipping the whole mattress, a two-person job unlike a snap-on fitted protector

Frequently asked questions
SureGuard vs Linenspa Zippered Encasement?
Buy SureGuard when the stakes are real — if you've had bed bugs and never want a repeat, the lab certification and 10-year warranty are worth the extra ~$9 over Linenspa. Choose Linenspa (~$28) if you want six-sided, bed-bug-proof protection as a precaution and don't need the certification paperwork or long warranty. Same core seal; SureGuard is the insurance policy, Linenspa is the value play.
SureGuard vs SafeRest Premium Protector?
Different tools entirely. SafeRest is a fitted, top-and-sides protector that's plush, quiet, and snaps on in seconds — it handles spills and sweat, not pests. SureGuard is a full encasement that seals out bed bugs and dust mites but feels firmer and takes two people to install. If accidents and comfort are your concern, SafeRest; if it's bed bugs or serious allergies, SureGuard — there's no overlap in what they're for.
Is the 10-year warranty worth paying more for?
If this is long-term bed-bug defense, yes. An encasement only works if the zipper and seams stay intact for the roughly 12–18 months a bed bug can survive sealed inside, and often longer as ongoing protection. A 10-year warranty signals SureGuard expects its closure to last that long. For a one-time precaution, the shorter-warranty Linenspa saves money without giving up the seal.
Will it change how the bed feels?
Yes, somewhat — it wraps all six sides in a waterproof fabric shell, so the mattress feels a touch firmer and less breathable than bare, more so than under a soft terry pad. That's the honest cost of a certified seal. Layering a comfort-focused mattress pad on top brings back the plush feel while keeping the encasement's protection fully intact.
