We got the i8 bed. We were hesitant at first because of the price but we wanted to get a bed we knew would be comfortable for both myself and my husband. The bed is soft enough for me and firm enough for my husband. It does have a cooling effect to it.

I just bought this month, and I was amazed how easy it was to get help. We tried a few, but I chose this one for the cooling feature.

We bought the bed about 2 months ago and have really enjoyed the ability to adjust the firmness of the bed. It’s been amazing.

I bought this bed because I always woke up with a backache on a conventional mattress. Since purchasing the sleep number I8…I no longer have a backache. The auto adjust feature adjusts the bed to me. I can also use the bio meters of the sleep iq to improve my sleep.

I bought it a week ago and can’t wait to get it.

I purchased this bed over 30 days, and I wake up feeling like I slept on clouds. My neck and back doesn’t hurt in the morning. I travel a lot and I really miss my bed when I’m away. I love my sleep number
