    Lindsey Clement asks:
    Question about Sealy Posturepedic Diamond Bar 11.5" Plush :
    Right now I have a Serta that I hate. My husband is a big guy and we have a huge crater in the mattress where he sleeps and a hill in the middle. It is so uncomfortable. Would this be a good choice in mattress for us? Also I hate being hot when I sleep so I am considering the memory gel. Thank you
    Chris answered:
    This would be a great choice, the gel infused memory foam will help with the heat issues. Also, this mattress has a pocketed coil, so you should not have as much body impressions as the one you currently sleep on.

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.
