We gave the Kelburn II a 5.5 on our comfort scale out of 10, with 10 being the softest. This mattress has a fantastic soft on top, firm underneath feel that provides an excellent blend of contouring and support. The Sealy Immersion Advanced Memory Foam with Chill, a proprietary comfort material to Sealy, creates a body hugging level of comfort with great pressure relief, and a cool to the touch feel that keeps you cool while you fall asleep.

The Kelburn II features a smooth top stretch-knit cover with moisture wicking. This cover conforms very well to your body while providing an added benefit of moisture wicking to help promote comfortable sleep.

The Sealy Response Pro Zoned HD Encased coil system in the Kelburn II is great. It's contouring, supportive, offers great motion transfer reduction for undisturbed sleep, and most importantly, it specifically targets the lower back area for enhanced support and durability. It's also adjustable base friendly.

Temperature management is a big one here. If you tend to sleep warm, the Kelburn is going to help combat that problem so you can get to sleep feeling cooler. The top of the line edge support is also fantastic and provides uniform comfort from edge to edge. The warranty is nice, and comes with a 10 year non-prorated warranty, one of the best in the industry.

If you sleep on your side, yes, this mattress is most likely a great choice for you. The combination of body contouring pressure relief and solid support makes this one of the best performing mattresses at this price point. If you're a back sleeper, this is still a good choice, but you may want to consider the Sealy Hybrid Trust model, because it fared better for back sleepers. See how this mattress performed.
