Our take
Sunvivi's official product page offers a Beige King 90 x 100 inch variant and documents ten heat levels, 89–108°F, separate left/right controls, a 0.5–12 hour shutoff, double-sided 220g flannel, machine washing and a five-year warranty. Its general size paragraph conflicts with the variant selector, so the 90 x 100 inch option is the relevant evidence. Historical ASIN B0BRMM3KLX is not mapped; the page does not establish the source title's ETL claim.
Consider it for a King bed when separately controlled sides and flexible shutoff choices matter, after confirming the selected Beige dimensions and item identity..

What the features mean for you
Exact Beige variant and dimensions
Sunvivi's official page offers a Beige variant marked 90 x 100 inches, corresponding to the source's King Beige description. A separate paragraph elsewhere on the page gives different general sizing, so use the variant selector for this particular option and do not rely on the conflicting broad specification. The page does not map historical Amazon ASIN B0BRMM3KLX to the current product. Check the exact selected Beige/King option and its dimensions before purchase. No personal fit test or coverage measurement is claimed.
Two independently controlled sides
The official product page describes separate left/right controls for the blanket. That is stronger evidence for two separately adjusted sides than simply observing two controller plugs. Confirm that the exact offer is the Beige 90 x 100 variant and check the instructions for how the two controls work. This can matter to two sleepers with different preferences, but it does not guarantee any particular comfort result. No user test is claimed.
Ten levels and temperature range
Sunvivi lists ten heat levels with temperatures from 89°F to 108°F. These are manufacturer-provided specifications. They help compare the model's stated adjustment range with blankets that provide fewer steps. The page does not establish measured temperatures across the entire surface or guarantee a particular sensation at each level. Use the range as the maker's stated specification and follow the exact controller instructions. No warm-up test or independent temperature measurement was performed.
Timer and fabric
The official page specifies shutoff options from 0.5 to 12 hours. It also describes double-sided 220g flannel. The 220g phrasing is a maker specification; the saved page does not explain how weight is measured. If you need a shorter timer or a particular surface feel, verify the controller choices and exact fabric on the current product option. The timer range is not a statement that every interval is selectable continuously unless the controller instructions confirm the available choices. No tactile, warmth or durability assessment is claimed.
Washing and warranty
Sunvivi's official page says the blanket can be hand or machine washed and lists a five-year warranty. Follow the full instructions for detaching controllers and drying. Confirm that warranty terms apply to the seller, region and exact selected item. These maker-page claims are not independently tested here. The frozen source title also mentions ETL certification, but the saved official page does not establish that listing; do not treat ETL as verified without a relevant certification record.
Amazon identity still needs a crosswalk
The manufacturer page supports a current Beige 90 x 100 inch variant and its specifications, but no source maps that variant to historical ASIN B0BRMM3KLX. The Amazon page returned a cache miss. Search by product attributes below, then confirm the current listing and selected color/size. If exact direct identity is required, check the product and manual identifiers before ordering. No current price, stock, sales rank or buyer-review summary is claimed.
Who should consider this blanket
This is a useful option for someone who wants a King blanket with separately controlled sides, ten listed levels and a broad selectable shutoff range. It is less suitable for a shopper who will not proceed without a mapped Amazon child or verified ETL record. Confirm that the offer is the Beige selector choice and check the conflicting general size paragraph. No personal test or performance ranking is claimed.

The decision
Sunvivi's official product page offers a Beige King 90 x 100 inch variant and documents ten heat levels, 89–108°F, separate left/right controls, a 0.5–12 hour shutoff, double-sided 220g flannel, machine washing and a five-year warranty.
