We know choosing a mattress can be difficult, but Helix truly includes a mattress for everyone. In addition to the 6 different firmness levels, they additionally have Helix Plus and Birch from Helix (sizing info on Birch is handled on this page). The Helix Plus is specially designed for heavier sleepers, while the Helix Birch is their only organic offering.

Which Helix mattress to choose?

The two main lines of Helix mattresses – Helix Standard and Helix Luxe- are divided into three different firmness options: soft, medium, and firm. Helix mattresses are available in two variants, depending on your preferred sleeping position. One is designed for side sleepers; the other for back and stomach sleepers. Once you know that, choosing the right Helix mattress is very easy. However, you can also take the Helix Sleep Quiz. This will find you the right mattress within minutes, depending on the answers to some questions about your age, height, sleep preferences, etc. (If you’re sharing a bed, you can also fill in your partner’s contact details.) Finding the right mattress has always been difficult. Many companies seem to be promoting themselves as a one-stop solution to sleep problems. These claims are simply not correct, as everyone has different requirements and tastes. With all the options available in the market today, finding the perfect mattress can be difficult and can take some time, if not a little trial and error at least.

Helix Sunset Mattress Dimension guide

The Sunset is the lightest mattress in the regular Helix Sleep collection. It is the most conventional memory foam texture and shapes around the body larger than any other normal Helix mattress, making it the best mattress for side sleepers. The Sunsets comfort cover includes soft memory foam, so you will feel hugged and lying down, especially if you sleep on your side. Helix designed the mattress to provide side sleeper assistance for short body types, but medium-weight sleepers who like an extremely plush feel might find it comfortable as well. Although it shares a similar stability setting in the Helix Moonlight.

Helix Moonlight Mattress Dimensions 

The Helix Moonlight mattress is promoted with the Sunset as with a soft feel. While it’s soft, it doesn’t have a sinking feeling that memory foam purists tend to like. It uses the manufacturer’s exclusive Helix Dynamic Foam from the Relaxation and Transition layers, which collectively create neutral, soft buoyancy for your sleeper. This mattress is ideal for small back and stomach sleepers, but we also suggest it as a mattress for mixed sleepers who change mainly with the stomach and back. The Helix Moonlight can also do the job for little side sleepers who don’t like a memory foam texture.

Helix Midnight Mattress Dimensions

The Helix Midnight is your brand’s most popular version, using a moderate level of firmness that might be suitable for back, side, stomach, and mix sleepers. It’s a traditional memory foam texture reminiscent of Tempur-Pedic mattresses, but it’s responsive and inviting thanks to the pocket coil center and the dynamic Helix latex-like foam transition coating. The flexibility of this Helix Midnight also makes it one of the best mattresses for couples who fall into the midweight category. The Helix Dusk, the maker of other moderate firm mattresses, has a neutral foam feel and also a bit more support. If you’re struggling to choose between the two, we recommend Midnight for people with ailments and pain.

Helix Dusk Mattress Dimensions

Much like the Helix Midnight, the Dusk is a hybrid mattress using a moderate level of firmness. On our mattress stability scale, we think the Midnight as well as the Dusk collapse around a 6/10 degree of hardness: moderate stability. On the other hand, the Dusk is meant to feel like a more even-handed lather than the texture of Midnight’s memory foam. Helix accomplishes this by putting its own responsive and inviting Helix dynamic foam on the Dusk’s comfortable liner. Despite the fact that you won’t experience as much stress relief as on the softer Midnight or Sunset mattresses, you will likely feel encouraged in any place to sleep under Helix Dusk.

Helix Twilight Mattress Dimensions

From the second firmest mattress in the normal Helix Sleeps line, the Twilight offers a professional feel but offers pressure point relief with the help of a top layer of memory foam. If you sleep soundly, mostly on your side, but appreciate a firmer mattress, this could be a fantastic alternative for you. The Twilight is a fantastic mattress for back and stomach sleepers who want a firm mattress but also need pressure relief to avoid aches and pains. The Twilight will feel more welcoming than the Dusk and Midnight beds (each of which have moderate firmness), but it’s not likely to feel as firm as the Helix Dawn.

Helix Plus Mattress Size

The Helix Plus was created for individuals “and size” (and has been called the Nightfall), is a more substantial mattress compared to Helix’s other choices. It is moderately firm and should hold up well to many sleepers, including individuals weighing over 91 kg. Additionally, we believe that despite its title, it is acceptable for sleepers who are planning a lot less, as the harder construction results in a classier mattress and a feel that might appeal to a larger audience. The Helix Plus is created with three layers of foam, all denser than almost all of Helix’s additional 13 mattresses. The top cover, which is generally the most vulnerable to wear and tear of almost any mattress, provides a polyfoam density of 1 pound per cubic foot, compared to two 1/2 or two 3/4 pounds per cubic foot in other offerings. from Helix. The memory foam in the next layer is real memory foam. The foam layers were held together by 968 individually wrapped spools.

How to Measure your Helix Mattress

There’s no such thing called the perfect size for a mattress. The main reason is that choosing the right mattress size is mainly a choice based on personal preferences. Take the measurements of your room also into account when choosing your Helix Mattress Size.

Time needed: 3 minutes

Measure your mattress size in 6 simple steps, with extra steps to be sure you have chosen the perfect bed for your sleep

  1. Make sure your mattress is free of blankets, sheets, and pillows

    It is best to measure the correct size of your mattress when there is absolutely nothing on it. If there is a comfort layer on your mattress, feel free to leave it.

  2. Measure the width of your mattress from left to right.

    Mattresses can bend towards the ends, so be sure to measure from the ends of each side of the mattress.
    Use a flexible ruler or tape measure when measuring. Write the measurements on a piece of paper so you don’t forget them.

  3. Measure the length of your mattress from the foot end to the head end.

    When your mattress deflects at the head and foot end, be sure to measure the furthest point from each side.

  4. Measure the height from the bottom to the top of the mattress

    When you have a comfort layer on your mattress, feel free to leave it in your measurement. If not, only measure the height of the mattress.

  5. Apply these measurements in the size tables below of this article

    These measurements will help you choose the standard size of the mattress of your choice. The standard Helix Mattress sizes are Twin, Twin XL, Full, Queen, King, California King and Split King

  6. Extra: Measure the doorways and hallways in your home before purchasing a new mattress

    This is a very important dimension because you have to be absolutely sure that the mattress of your dreams. Choose the width of your mattress so that it can pass through the lowest doorway in your house where you have to carry it. Many mattresses are delivered in a box, so this problem occurs less these days
    Pay attention to the width and height of stairs that you have to pass with the mattress

  7. Extra: Measure the bed frame before you buy the mattress.

    This sounds logical, but it is recommended that you also measure your bed frame. Or when you buy a separate bed frame, it is best to check the dimensions, as these can vary from different manufacturers.

  8. Extra: Measure your room

    Make sure there is enough space around the bed or mattress you plan to buy. This space is preferably provided along 3 sides of the mattress so that you can walk smoothly past your bed. We have written a separate article about this topic.

Remember that height/thickness varies depending on the Model, so there is no universal thickness for each mattress size.

Helix Mattress Thickness : How thick is the Helix Mattress?

The term “mattress thickness” is the same as “mattress height” and “mattress depth.” The Mattress thickness is only a part of the overall height of your bed. When your mattress is on the floor it’s the complete height of the bed.

Material Thickness is the vertical dimension of a mattress. (height of the mattress)

Frequently Asked Questions about Helix Mattresses 

Would You Need A Box Spring Using A Helix Mattress?

While it is not essential to create a comfortable mattress, a box spring improves the durability of your mattress and also protects it from mildew. The warranty for most typical Helix mattresses takes a support base with clamps spaced no more than 13cm apart. Platform bases, flexible foundations, and box springs are acceptable as long as they provide sufficient support for your mattress.

What Is The Motion Insulation On A Helix Mattress?

None of the normal versions of Helix have thick, ultra-absorbent foam layers like those found in a memory foam mattress, but some models’ ability to distill movement varies depending on comfortable foam shape and depth. For example, the Sunsets soft memory foam surface absorbs more movement and sound than its softer counterparts featuring Helix Dynamic Foam at the top.

How Long Can A Helix Mattress Go On?

We expect Helix mattresses to last seven to ten years.

How Can The Helix Sleep Quiz Work?

The quiz on HelixSleep.com matches a customer using the manufacturer’s best mattress using sleep patterns and biomechanical data. To get your recommendation, you will then answer a few questions about your tastes, your body type, and your sleeping place.
