{"product_id":"jamison-sleep-response-premier-firm-mattress","title":"Jamison Sleep Response Premier Firm Mattress (Online Exclusive)","description":"\u003ch2\u003eThe firm one in the Sleep Response foam lineup\u003c\/h2\u003e\u003cp\u003eThe honest verdict: the Premier Firm is for the back or stomach sleeper who wants to rest on top of the mattress, not down in it, and who has given up on firm beds that trap heat. Jamison rates it a 7 out of 10, where 10 is the firmest. That is real firm, with a thin gel comfort layer up top so the surface has some give before you reach the high-density LuxFirm Foam that does the holding. If you want an all-foam bed that stays level under your hips, start here.\u003c\/p\u003e\u003cp\u003eAt 11.5 inches it sits between the trim 8-inch \u003ca href=\"\/products\/jamison-sleep-response-react-cushion-firm-mattress\"\u003eReact Cushion Firm\u003c\/a\u003e and the taller hybrids. The React is rated an 8 and feels harder at the surface. The Premier Firm is a step softer on top and puts a lot more foam under you, which matters if you are a heavier sleeper or you share the bed. It is also the only firm model in the Sleep Response line with the IceTech Cooling Fabric cover, so if you want cool and firm, start the comparison here.\u003c\/p\u003e\u003ch3\u003eWhat is inside, and what it does for you\u003c\/h3\u003e\u003cp\u003eTop to bottom: IceTech Cooling Fabric on the cover, which feels cool when you first lie down. Under it, Safe Slumber fire retardant fibers meet the federal open-flame standard without chemical flame retardant sprays. Then DualComfort Foam with gel, the layer that takes the edge off so the bed does not feel like a board at the shoulders. Then LuxFirm Foam, a high-density layer that keeps your hips from sinking below your shoulders. The DualCore Support Foam Core sits at the bottom and carries the load. Jamison has been making mattresses by hand in the USA since 1883, and Sleep Response is its factory-direct line built to ship.\u003c\/p\u003e\u003cp\u003eBecause it is all foam, there are no coils to carry motion. When a partner rolls over, the movement stays mostly on their side.\u003c\/p\u003e\u003ch3\u003eWho it fits, and who should keep looking\u003c\/h3\u003e\u003cp\u003eBack sleepers who want a level surface. Stomach sleepers, who need the hips held up so the lower back does not arch. Heavier sleepers who found softer foam beds bottoming out. Couples where one person moves around. Side sleepers may find a 7 firm enough to press on the shoulder, so if you spend most of the night on your side, look at the plush \u003ca href=\"\/products\/jamison-sleep-response-4-star-mattress\"\u003e4-Star\u003c\/a\u003e instead. It shares the IceTech cover and is rated a 4. If you want firm with coils under it, the \u003ca href=\"\/products\/jamison-sleep-response-apex-pro-cushion-firm-mattress\"\u003eApex Pro Cushion Firm\u003c\/a\u003e is the hybrid version of this idea, an inch and a half taller and rated an 8.\u003c\/p\u003e\u003ch3\u003eHow buying it online from Mattress Overstock works\u003c\/h3\u003e\u003cp\u003eThis is an online exclusive.
