SureGuard Mattress Encasement (Bed-Bug Proof)
Best for: Anyone with a real bed-bug history or a severe dust-mite allergy who wants a brand-described bed-bug and dust-mite barrier with a 10-year warranty rather than a value-tier seal.
The serious encasement — a six-sided zippered shell the brand says blocks bed bugs and dust mites, GREENGUARD Gold certified, 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, described by the brand as bed-bug proof and dust-mite blocking, and GREENGUARD Gold certified for low chemical emissions, backed by a 10-year warranty most rivals don't touch. The tradeoffs are the encasement tradeoffs, amplified by the price: at ~$65 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
- GREENGUARD Gold certified, which covers low chemical emissions; the brand describes the bed-bug and dust-mite barrier as a design feature, not a separate certification
- 100% waterproof across all six sides, so the entire mattress is sealed against liquid, not just the top
- 10-year warranty, per the brand (Linenspa lists a 10-year limited warranty too)
- 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
- It's the priciest encasement on this list — nearly three times the Linenspa's price for the GREENGUARD Gold certification
- 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 GREENGUARD Gold certification is what the premium over Linenspa buys; both list a 10-year warranty. Choose Linenspa if you want a six-sided encasement the brand says guards against bed bugs, as a precaution, and don't need the GREENGUARD Gold certification. 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 a reason to pay more?
Not on its own. SureGuard lists a 10-year warranty and Linenspa a 10-year limited warranty, so the warranty is not what the price difference buys. It still matters: 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, so keep the receipt whichever you buy.
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 tradeoff of a full six-sided seal. Layering a comfort-focused mattress pad on top brings back the plush feel while keeping the encasement's protection fully intact.
