In this section, let us review how Sleep Number i8 and the Nectar mattress feel for a wise choice ahead.
Since the I8 is a highly advanced mattress perfect for all body types and weights, light to heavyweight sleepers can enjoy sleeping in this bed. They can even change the firmness option of the mattress to match their preference. On the other hand, the foam mattress of Nectar is suitable for light to average-weight sleepers for that equal support and comfort sensation.
Since the Sleep Number i8 mattress has firmness options that you can specifically curate for your preference, you can choose whether you want it doughy or have that lifted feeling. In contrast, the Nectar mattress may provide you with more of a lifted and, at the same time, body-hugging cushion due to its foam mattress.
The Sleep Number i8 is best for all body types, even for heavy sleepers. Combination sleepers can feel supported while also being comfortable sleeping on this mattress. On the other hand, the Nectar mattress is best for light to average-weight back and side sleepers. Those with hip and joint pains will feel support from their shoulders to their hips.
Sleep Number i8 Performance By Body Type & Sleeping Position:
Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
Lightweight (< 130 lbs): | 5 | 4 | 5 |
Average-weight (130–230 lbs): | 5 | 3 | 5 |
Heavyweight (> 230 lbs): | 4 | 2 | 5 |
Nectar Performance By Body Type & Sleeping Position:
Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
Lightweight (< 130 lbs): | 4 | 3 | 3 |
Average-weight (130–230 lbs): | 4 | 3 | 5 |
Heavyweight (> 230 lbs): | 2 | 2 | 3 |
1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent
Average-weight side and back sleepers can benefit from the pressure-relieving foam mattress of Nectar. This mattress is perfect if you have hip and joint pains. Meanwhile, since the i8 is an innovative mattress, it is perfect for all, especially for combination sleepers who like to toss and turn.
Nectar mattress’s contouring layers are specially intended to maintain your spine in alignment, making it a good choice for side sleepers of average to heavyweight body types. On the other hand, those who weigh a lot to lay on their side or stomach may not get enough of it in the Nectar. Those who weigh a lot should look for a sturdy bed that can hold their weight without sagging as they sleep. The i8 may be suitable for heavier side sleepers who prioritize deep contouring sensations around the hips and shoulders.
Those who are lightweight back sleepers or of medium weight should discover that they maintain spinal alignment by lying on the top of the bed. The pressure-relieving properties of the Nectar may not fully manifest for this body type who won’t be able to sink all the way to the bed’s top layer. Only a tiny percentage of Nectar users will experience significant pressure while lying on their sides. The i8, on the other hand, will have a fluffier feel and make you sink deeper into the bed, making it a better option for side sleepers who often require more pressure relief.

The i8 mattress has a Smart 3D fabric mattress cover for that advanced mattress technology. On the other hand, the Nectar mattress has a soft plush cover for extra cushion.

In this section, we will describe how these two mattresses compare for an informed mattress preference.
The i8 mattress has advanced cooling technology, perfect for those who sweat excessively when sleeping. It is cooling and suitable for light to heavyweight sleepers. Meanwhile, the Nectar can absorb heat since this is a foam mattress. This mattress is suitable for those who get cold quickly when sleeping.
Movements can be isolated from both mattresses, which makes the i8 and Nectar mattresses suitable for couples. However, suppose you are a couple with different preferred softness on their mattresses. In that case, the i8 may be the perfect match for you since you can have the division, thus isolating motion more efficiently.
Sleep Number beds have air chambers that reach right to the edge, so you’ll have plenty of support whether you like to sit on the side or stretch across the entire surface.
The i8 mattress is best suited for lighter or average-weight sleepers due to its softer feel and deeper sinkage. On the other hand, pressure points will feel perfectly cradled by Nectar’s medium-firm texture.
A Sleep Number bed may help you get a good night’s rest even if you have chronic discomfort from your joints or spine. The foam layers of the i8 mattress work to spread your weight throughout the bed, thereby reducing pressure points and the associated pain they can cause. The Nectar is a good choice if you regularly have soreness in your shoulders and hips because it provides adequate pressure relief to cushion even average-weight side sleepers. Individuals who suffer from back pain, especially in the lower back, should purchase a mattress like the Nectar, which is firm enough to keep the hips and lower back elevated when sleeping.
Regarding durability, the Nectar mattress is known to last for up to 7 years. On the other hand, the i8 mattress may be more durable, lasting 10 years.
No cost for shipping or the optional white glove delivery service comes with every Sleep Number bed. If you decide to keep the bed after the 100-night trial period, you will be covered by a 15-year warranty. Please be aware that this is a limited warranty and that any service after the first year will increase in price for you.
Free shipping applies only to the 48 contiguous states. Nectar mattresses are 11″ high, making them heavier than other bed-in-a-box options. For a fee, Nectar now provides a “white glove” delivery service. There’s a full year (365 nights trial period) to try it out, and the warranty lasts forever.
If you want a budget-friendly mattress, you can opt for the Nectar mattress, which is suitable for those who are back and side sleepers experiencing joint and hip pains. However, if you are a heavyweight sleeper who requires more support and a combination sleeper, you might want to choose the i8 mattress. It might be pricier, but the benefit it offers is extraordinary.
While all Sleep Number beds feature SleepIQ technology, the degree and type of comfort foam used in their construction varies widely. As a result, some beds provide more pressure relief than others, giving the impression of deeper contouring and cushioning, while others provide more support.
Yes, as long as you are a proud owner of this mattress, the company states they will take full responsibility for its durability. Monday-Friday, 8 a.m. to 4 p.m. PST, they are available by web chat or email. They will guide you through the steps.
Considering your budget when purchasing a mattress, you can opt for the Nectar mattress since it’s more budget-friendly. However, if you do not care about price and want highly advanced mattresses, you can directly choose the i8 mattress.
