Quick verdict
Yawnder Reviews
The Nolah Luxe Alaskan King is a 108-by-108-inch hybrid intended for people who need far more room than a standard king. Its large footprint is its defining feature, but it also means measuring the bedroom, delivery route, frame and bedding before buying.
Size and construction
Nolah currently lists the Luxe Alaskan King at 108 inches wide, 108 inches long and 13 inches high. For context, a standard king measures approximately 76 by 80 inches. The difference is 32 inches in width and 28 inches in length; plan for walking space and furniture as well as the mattress footprint.
According to Nolah, the current model uses foam layers, a GlacioTex cooling cover and an eight-inch pocketed-coil core. The company describes its feel as Luxury Firm, approximately 6–7/10. It lists GREENGUARD Gold certification for the mattress and CertiPUR-US certification for foam; those programs cover different things. See the current product listing.
Yawnder’s recorded scores
Yawnder’s existing record lists an 8.4/10 overall score, with 6.5/10 firmness, 8.7/10 cooling, motion isolation and edge support, 8.5/10 pressure relief, 8.3/10 response and 7.6/10 spinal alignment. The record is dated August 26, 2026, but does not document the tested production version or underlying measurements here. Treat these numbers as existing editorial data, not a guarantee of current performance. Its 8/10 durability entry is an expectation rather than evidence of long-term use.
The old page also listed a queen reference price; that is not an Alaskan King price and has been removed.
Delivery and setup
Nolah says the current mattress arrives in three boxes with compressed components for assembly. Check the delivery route, stairs and doorway clearances for each box, and make sure the assembled mattress can fit the room. Follow the manufacturer’s setup instructions; Nolah recommends that two adults assemble the mattress.
An Alaskan King requires a compatible 108-by-108-inch foundation and correctly sized sheets and protector. Check the frame’s support and weight requirements; standard king bedding and bases will not fit.
Who should consider it?
Couples who want room: The added width can create more personal space, provided the room still has comfortable circulation around the bed.
Tall sleepers: The 108-inch length offers more foot room than a standard king or California king. Measure the room before assuming the extra length is practical.
Families with pets or older children: The surface is spacious, though more occupants can mean more movement and bedding to wash. Follow safe-sleep guidance for infants; a large adult mattress is not an infant sleep surface.
Price, trial and warranty
Nolah’s direct product page currently advertises a 365-night mattress trial with a 30-night break-in period and a limited lifetime warranty. Promotions and price change, and the 108-inch model may have particular shipping or return conditions. Confirm the final Alaskan King price, pickup rules, any fees and your seller’s terms before purchase.
