Sealy Optimum 10 Radiance Reviews

Avg. Rating: 4.4/5
  • Brenda Says:
    First, I just want to say that Mattress Firm's service exceeds all others! After numerous hours of research and trying out different mattresses in stores, I am very pleased with my Sealy Optimum. I have a herniated disc in my lower back and for the first time in years, I wake up without my back hurting. I have owned my mattress for one week and am very happy. I don't feel my husband getting into bed later than me and my quality of sleep has improved. The foam has been cool and thought that I would need a firmer mattress but this has been great in my first week of ownership. Megan, the sales rep, was very knowledgeable and not pushy; a wonderful sales rep who even had our mattress delivered on a Sunday afternoon (the same morning I ordered it). I have decided to stay with Sealy above all because of their expertise and knowledge along with their commitment to quality. In addition, my experience with Mattress Firm was so wonderful, I plan to make all of my future purchases with them and refer my friends and family to them:) My conclusion is to only buy a mattress from a reputable mattress store and a name brand that speaks for itself.
  • Richard Says:
    We remain hopeful this will be a good purchase and last the standard 8-years recommended for mattress replacement. The warranty is great! The price and incentives were great as well! We like firmness in a bed, but not too firm, and really were interested in trying gel and memory foam technology. We retired a 10-year old pillow-top that was worn out! Next day delivery was awesome... Anyway after the first night, we're not sure it is the answer to sleeplessness and minor 'wake-up' pain, but we plan to allow some break-in time and will re-post if it is worthy of a 5-star rating or if we discover the need to exchange it. Another concern is that there are very few on-line reviews of this product compared to other gel/foam mattresses out there.
  • Bill Says:
    It seemed firm in the store, but is too soft after sleeping on it for less than two weeks. My back pain returned. This mattress may be fine for some, but is unsatisfactory for me.
  • Ronnie Says:
    I would like to say we have had this mattress for about 3 months.We would like to say it's the best mattress we've ever owned.I would recommend to any one.It keeps u cool at night and contours to your body which you will get a great night sleep.
  • Don Says:
    Had mine for over a year and it's great. Firm but not hard. No more back pain Very happy !!!!

Twin Size Mattresses

Twin mattresses can accommodate one child or one adult sleeper although the length of the mattress might be too short for an adult. Twin size mattresses are used for children’s rooms, bunk beds, daybeds and smaller spaces such as guest bedrooms.


Twin XL Size Mattresses

Twin XL 39"x80"

Twin XL mattresses are great space savers and are commonly found in dorm rooms and offer an additional five inches of length to your sleeping space.


Full Size Mattresses

Full 54"x75"

Full or double mattresses provide more width for your sleeping area. A full size mattress is ideal for one person. If you divided the mattress in half two people would only have 27 inches of sleep space (or the equivalent of a crib mattress).


Queen Size Mattresses

Queen 60"x80"

If you prefer more living space in your master bedroom, a queen size might be what you are looking for. Also, queen mattresses are ideal for someone who likes additional width and height while sleeping; which makes it a great choice for growing children and taller adults.


King Size Mattresses

King 76"x80"

If you have the space in your bedroom, a king size mattress is the best choice for couples; you each have a sleeping service equivalent to a twin extra long mattress. It is also great for growing families or pet owners.


California King Size Mattresses

California King 72"x84"

If you are looking for additional length in your sleep surface, a California King might be what is right for you. Four inches of width are taken from a traditional king mattress and added to the length.


Mattress Comfort Level

Firm mattresses offer the least surface “give” and would be considered harder in feel to the other mattress surfaces. If you like a solid feel rather than soft, firm may be your choice.

Plush mattresses offer more surface "give" and provide a softer surface comfort. This is a happy balance between firm and pillow top.

Pillow Top mattresses provide the ultimate in surface comfort and firmness, cradling and supporting your every move with pillow like softness while you sleep.

Contoured mattresses provide pressure relieving support by conforming to your body. It is firm where you need it and soft where you want it.

Personalized mattresses are customized to your unique body type and sleep needs.


Low Profile Foundation

A low profile foundation is 4.5" to 5.5" in height and is helpful if a high profile (standard) foundation causes your bed to be difficult to get into and out of easily. A low profile foundation can also help your mattress from covering a low headboard.


High Profile Foundation

A high profile (standard profile) is 8" to 9" in height and is the most common height used for a foundation.
