  • First Memory Foam Bed, and it's GREAT!!!

    (To clarify, I did not order this bed from Overstock (tho I am an Overstock customer) because I needed immediate delivery and full set up, so purchased locally, At my local vendor I paid about $$$ in Nov 2012 - there may have been a mfgr's promo in this price, since this is a new product in 2012.) This review, therefore, is on the bed only. I am a 60 yo female, weigh about 240, and do not share this bed with a partner. My back has troubled me for some time, which I had written off to aches and pains of aging. However, sleeping on the Optimum Radiance Queen (now for 90 days) has been a GREAT experience. I have not had back or neck pain since I bought it, and I did not require the adjustment period often referred to in other reviews. [I use a roll neck memory foam pillow from Ikea ($25), and I am a side sleeper.] Slept like a ROCK the first night. I experienced no off-gassing, and do not find a memory foam bed any "hotter" than any other bed I have ever slept in. Maybe this is due to cooling gel in this bed; maybe not. (Hot? Toss Covers!) It is an adjustment to get used to getting in and out of the bed, and re positioning in the bed, because there is no 'bounce' such as we are accustomed to in inner spring mattresses.You literally have to lift or roll your entire body weight by your own strength, since the foam does tend to "suck you back in." I will say I no longer feel I can sit on the edge of the bed to put on my shoes -- so have placed a chair nearby for that purpose. It's not that you CAN'T sit on it; it's just that I want to avoid excess wear on the edge foam; and that the chair is more rigid and secure. When I get in this bed at night and - more important -- when I get up in the morning -- I feel absolutely great. I am VERY HAPPY with this mattress.
