Mattress comfort levels vary by manufacturer, but there are some generally accepted comfort levels that you can use as a guide to buying a mattress. Comfort levels range from firm to very plush. You can expect similar levels of support from all comfort levels, but the softness will vary. At the firm end of the comfort spectrum, you will be sleeping on a hard surface with very little body weight displacement. At the soft end of the spectrum, you will the find plush, ultra plush, pillow top and euro top comfort levels, in increasing levels of cushioning. The “Sleep Number 4000” and “Sleep Number 5000” mattresses are at the pillow top and euro top comfort levels.
The Sleep Number 4000 mattress is a special pneumatic, pillow top mattress from Select Comfort. It is made with a special firmness control technology, which uses adjustable air pockets or chambers to allow you to control the firmness on each side of the bed with a remote control device. It has a ten-inch thick mattress and a plush European-style pillow top and five comfort zones. The 4000 model has been superseded and the new model is called the c4.
The Sleep Number 5000 mattress is a pneumatic mattress from Select Comfort that has an eleven-inch thick pillow-top mattress. It allows you to individually control the firmness and comfort of each side if the mattress by changing the pressure in adjustable air chambers inside the mattress using one of two supplied remote controls. It has a two-inch layer of luxury foam in the pillow top for added comfort and comes with three comfort zones. It has been superseded and the new model is known as the p5 mattress.
Your weight is a primary consideration when choosing the comfort level of a mattress. Very soft or plush mattresses might not provide sufficient support if you are very heavy, so a firmer mattress is a good choice for you. The Sleep Number mattresses are thought to be a good choice for couples who share a bed, as they can adjust the firmness on each side of the bed to better suit their sleep preferences and weight requirements.
