Size Of The Bed Room
The size of your bedroom is crucial when choosing a mattress. Trying to fit a King size mattress in a small room would make the space look cramped up and would not leave any room for extra furniture. A twin-size mattress in a master bedroom would make your space look empty. Hence, choose your mattress size as per your room size and not just have a comfortable sleep but also make your room look aesthetically beautiful.
Body Weight And Height
A medium firm or firm mattress is perfect for all body weight. If you wake up with body aches or sore muscles then kindly consult your Orthopedic or Chiropractor before buying a new mattress.
Sleeping Position
Your and your partner’s sleeping position needs to be considered before you buy a mattress. A wider mattress like King or California King mattress would be ideal if you like to have personal sleeping space or stretch out. Whereas a Queen mattress would be an excellent choice for those who like to cuddle and sleep.
Budget
The rule of the thumb is that the bigger the mattress, the more expensive it will be. However, this can change depending on the brand, the material, and its technology.
Frequently Asked Questions
There is no “Best” bed size, only what’s best for you. Take into account how big your bedroom is, how much walking distance you need around the bed, furniture in the room, and how much space you need when you sleep (ie, do you sleep curled up like a baby, or like to stretch out!). Also keep in mind if you are single or share a bed with a partner and/or pet. While you need enough space, the most important consideration for your rest is sleeping on a comfortable and supportive mattress. Use our mattress dimensions guide to see which Nectar is right for you.
Most couples choose to have a King or California King sized bed based on preference for more space for each person. However since space can be limited, the next most favorable bed size for couples is a Queen. Anything smaller than a Queen size is going to be a tight squeeze for two, and you will feel each other moving around at night. A King size Nectar memory foam mattress reduces motion transfer significantly and provides ample space, so you’ll get a great night’s sleep even when sharing your bed with partners and/or pets.
You should get the sized bed that fits your room best. Use our mattress guide to help you determine the best size mattress for your room.
Some couples like to sleep in a smaller bed to feel close and cuddly, while others prefer a little space. Sleeping well with your partner is helpful for all couples. Feeling your partner toss and turn, or feeling crammed into bed, won’t be fun for anyone. When you wake up well-rested, you’re more likely to have better days with your partner which can help you have a happy, healthy marriage. With a bed like Nectar, which helps reduce motion transfer and has a quilted cooling cover, you and your partner will be well-rested every day!
A Full sized bed is big enough for two people, but it is not recommended for couples. A Full sized bed is ideal for a child, and a parent reading a bedtime story, or a person and their pet – but not two adults who need room to move around at night or have different sleeping positions. For two adults, a Full size only gives you 27″ of space each, which is likely not enough for most people to rest comfortably throughout the night. So remember – double’s are actually best for singles!
That depends. If measuring by cubic feet, a King mattress is the largest bed that Nectar offers, at 42.2ft3. A California King mattress from Nectar comes in at 42ft3.
However, a King mattress is 80in(L) x 76″(W) x 12″(H) whereas a California King is 84in(L) x 72in(W) x 12in(H). The California King mattress is 4 inches narrower and four inches longer than a King mattress, so it depends on the shape and size of your room.
It’s a popular myth however, two regular Twin beds do NOT equal a King bed. In fact, two Twin XL beds equal a King size and can be a good option for someone using two beds in a guest room that they can also push together if the need arises. Two regular Twin mattress are the same width as a King, but shorter in length by 5 inches.
No, you can not use a Queen mattress on a Full frame as it will not fit properly. A Queen is larger than a Full, so you’ll need a Queen size frame for your Queen mattress. It’s best to always match up your mattress, frame, and sheet sizes for the most comfortable night’s rest.
For two Twin beds pushed together, you are going to be hard pressed to find sheets that fit. A standard Twin bed is 38 inches wide and 75 inches long; a standard King bed is 76 inches wide and 80 inches long. However, two Twin XL beds pushed together is about the same size as a King bed and you could get away with King size sheets.
A standard Twin bed is 38 inches wide and 75 inches long; a standard King bed is 76 inches wide and 80 inches long. Therefore two Twin beds are not quite equal to a standard king bed. However, two Twin XL are equal to a King.
A good mattress should be 11 to 15 inches thick. Depending on the combination of foams, coils, latex, and covers, mattresses will vary in height. The thickness can affect how comfortable a mattress is, and Nectar has found that the ideal thickness for our mattress is 12 inches to achieve ideal comfort, softness, and support. We use multiple layers of premium contouring foams to build the most comfortable mattress. We found that a great mattress should be at least 11 inches thick, with luxury mattresses usually being 15 inches.
The average bed height is usually about 25 inches in total, including the frame, mattress, and any additional toppers or bedding. This is so your feet can reach the floor when you’re seated on the edge of the mattress.
