Summary
A washable fitted fiber pillow-top for Queen 60×80 in mattresses, built to soften a firm but otherwise sound mattress. Before you buy, know the layer: it is a thin comfort pad, not a thick foam topper, and it will not fix a sagging mattress.
Strengths
- Softens a too-firm but structurally sound mattress without the deep sink of memory foam.
- Deep fitted skirt for 8–20 in mattresses is easier to manage than loose foam and generally stays in place.
- Machine washable with low tumble drying, which can restore loft.
- The bamboo-derived rayon blend surface is positioned as breathable and moisture-managing.
- No recurring consumables; laundering is the only ongoing cost.
- OEKO-TEX Standard 100 certification number reported by an exact-model mirror.
Weaknesses
- Not a support layer: fiber fill cannot restore a sagging mattress or match a 2–3 in foam topper.
- No defensible exact thickness is published; buyers expecting a visibly thick layer are the most likely to be disappointed.
- Cooling is passive only, with no measured thermal performance for the exact model.
- Not waterproof; it is not a mattress protector.
- “Bamboo” is rayon derived from bamboo in 40% of the top fabric only, not the whole topper.
- Vacuum packing can make it look flat on arrival and it needs shaking and time to loft.

Full research notes and sources
Cooling and materials
The word bamboo covers less than it suggests: the top is 60% polyester and 40% rayon derived from bamboo, and the underside and skirt are polyester. That blend is breathable and moisture-managing, which some owners prefer to heat-trapping foam, but there is no active cooling layer and no measured thermal test for this model. Owner reports split both ways: some say it sleeps cooler than foam, others still report heat retention and even a slight change in stability, so treat cooling as passive rather than promised. Expect a temporary packaged odor that airs out; several family and community reports mention it.
Fit, care and repairs
The 8 to 20 inch fitted skirt manages thick mattress stacks and is generally reported to stay put, though occasional reports mention snug or incorrect sizing despite the nominal 60×80 in footprint. Care is simple — cold gentle wash, low tumble dry — and there are no consumables. A wet Queen-size fiber pad is bulky, though, and low-heat drying can mean more than one cycle in a small dryer. Repairs are not practical: the quilting, fill and skirt elastic are integrated, so damage normally means replacing the pad. Fiber fill can flatten with use, which is mechanically plausible but has no published failure rate for this model.
Prices and value
Niagara’s direct site listed the Ultra Soft line starting at $54.99, and exact Queen Dark Gray listings on eBay have shown about $47.23 and $67.58. Around the high $30s is the normal deal band: 2026 snapshots landed at about $37.99, $39.99 and $37.89. Below about $50 the washable plushness, deep-pocket fit and 365-night direct trial are strong value; around $51–$60 it is good, and $61–$70 is fair and starts to overlap with thicker options, including Niagara’s separate 2-inch Extra-Thick model at $59.99. Above roughly $100, foam and latex toppers with published thickness and more independent testing take over. The buyer is paying for washable plushness, deep-pocket fit and a breathable surface, not for structural support.
Which model this is
This page covers the Dark Gray Ultra Soft Queen, catalog model 215, GTIN 05060545020791, manufacturer part number 43396-309042. A current dark-gray listing shows MPN NB-MT-G-Q. Do not merge its evidence with the older Green Queen B07D5DN269: the two share a line and review history, but they are different colour variants and exact revision identity should not be assumed.
The US listing is ASIN B0FVYBPSWY.
