Flex Head Cal King Q9 Number Bed Mattress by Instant Comfort

The Q9 Number Bed Mattress by Instant Comfort® offers the most luxurious plush top with two-sided cover. This model features Platinum Thermacool technology for extra coolness. Dual chamber models adjust on both sides for individualized comfort. Perfect for couples who disagree on the firmness of the bed. With this bed you can each have the right firmness setting, you will sleep better, and your back and body will love you for it. The contouring support of the dual adjustable firmness technology helps keep your back in a more natural position and provides great spinal support.

For nights when firmer is better, you can simply increase your number setting and during other times when you need more pressure relief, you can select a softer number setting. Similar to an adjustable lumbar support in a car seat, the Q9 model can be adjusted to just the right number.

The ultra plush reversible top offers a bit more luxurious cushioning and pressure point relief. One side features the Platinum Thermacool technology for cooler sleep, and the other side features bamboo so you can adjust your temperature by reversing the top during the warmer and cooler months. Inside the top is 2-inch layer of gel infused memory foam for enhanced pressure point reduction, which causes you to have less aches and pains in the hips and shoulders. Thes model is great for side sleepers, back sleepers, and multi-position sleepers.

This Q9 model works with any adjustable bed base and is popular in the Flex Head size to fit any couples’ individual preferences. You can be raised up and your partner can remain flat when paired with an adjustable base. This mattress is 14.5 inches thick and includes a reversible pillow top and a reversible foam layer so you can customize your cushioning. The control system includes kink resistant hoses. The 24-gauge vulcanized rubber air chambers offer long lasting durability and this bed is backed with a 25-Year Limited Warranty. All components are replaceable and upgradable, so you’ll never have to buy another mattress, and it’s tested to last over 25 years. This model is available in all major sizes including Twin, Twin XL, Full, Queen, King, Cal King, and Flex Head size in Queen and King size.

You can also use the app on your smart phone to change your number, or the remote that comes with the bed at no charge, whichever you prefer. Get the bed you can adjust night after night and live in complete comfort. You can save hundreds with the Q9 Number Bed by Instant Comfort® available at Quality Sleep.
