Jamison Hudson Bay Medium Cooling Mattress

Cool to the touch, medium to the spine

Hudson Bay is where Jamison spends its comfort budget on temperature: a CoolTex cover that feels noticeably cool at first contact, over a balanced medium build that doesn't fight any sleep position. The Medium Cooling is for the sleeper who runs warm but isn't ready to pay national-brand-flagship money to fix it. It rates 5 out of 10, the honest middle, in a 13-inch profile with no pillowtop.

The cooling is real where you touch it, and the medium feel underneath covers couples and combination sleepers gracefully. Under the cover sit gel super-soft foam and a thin soft layer for surface give, then a 2-inch layer of EverFlow visco that conforms to your contours for spinal alignment, all carried by 686 zoned pocketed coils (Queen count) with support concentrated through the middle third where most of your weight rides. A durable support pad reinforces the coil system so the feel holds up for years.

What you notice in the first few minutes

Lie down and the cover registers first: a distinct cool-on-arrival sensation as the fabric conducts heat away from your skin, repeated each time you shift to a fresh spot. Then the medium takes over. The gel foam eases pressure off your shoulders and hips, the EverFlow visco fills in behind your contours, and the coil core pushes back just enough that you feel balanced rather than perched on top or swallowed up. That is what a true 5 out of 10 should do, on your back or your side.

That's also the difference from a cheap cooling bed, where the temperature trick stops at the cover. If you've owned a memory-foam bed and liked the contouring but not the heat or the slow, sink-in response, this build keeps the good part and drops the bad: the visco conforms for real pressure relief, while the responsive coil core keeps the surface lively instead of turning into that stuck-in-quicksand feel, and the cover keeps the heat down.

Who it suits, and who should look elsewhere

It's a strong pick for combination sleepers, since the balanced medium doesn't fight any position through the night, and one of the easier couples beds in the line, bridging a firmer partner and a softer one. Warm sleepers who want the cool surface but not a deep plush top land here naturally, along with side sleepers who run hot yet prefer a firmer, flatter feel than a pillowtop.

If you sleep mostly on your side and want a softer landing, this may read firmer than you'd like. The honest step up is its Cooling Pillowtop sibling, which adds a plusher landing to the same cooling idea on the same coil family, distinctly softer on the surface. If cooling isn't the priority, the Chandler Euro Pillowtop is the non-cooling comparison at a similar comfort level. Five minutes on each tells you whether the cover is worth it.

Living with it, and how to shop it

The pocketed-coil core flexes, so it bends comfortably on an adjustable base and works just as well on a sturdy platform, a slatted frame with slats no more than three inches apart, or a Jamison foundation. It carries a 10-year non-prorated warranty. Rotate it head-to-foot a few times a year to keep the surface even, and give it about three weeks to settle and your body to adjust before judging it.

To shop it, test the cover with your hand first, then your face: a showroom thermostat can't fake the cool-touch sensation. Then lie down in your normal position at any of the five Kentucky showrooms (Lexington, Richmond, Georgetown, London, and Somerset), no appointment needed, where the team can set it next to the Cooling Pillowtop so you feel the difference side by side. Because everyone on the Mattress Overstock floor earns the same no matter which brand you choose, the guidance is honest and never pushed toward one bed, and delivery, setup, and old-mattress removal are free across the Kentucky service area.
