Who Should Buy the Novilla 12″ Vitality Hybrid Mattress

I have divided the section into 3 parts:

  1. Sleeper Type
  2. Edge Support
  3. Motion Isolation

Is this mattress for you? it really depends on the type of sleeper you are and if you are single or you sleep with a partner.

Sleeper Type

First, understand the firmness, the mattress is medium firm and as per the brand the mattress is suitable for all sleep types.

If I talk about myself, I’m a back and side sleeper, when I sleep on this mattress, I find it very comfortable sleeping on my back and at the same time sleeping on my side doesn’t cause any pressure, whereas my wife is a stomach sleeper, and we both do not face issues regarding this.

I can say the mattress is suitable for all sleeper types.

Edge Support

If you are looking for a king mattress under $500, you have to compromise on a few things, you can’t get everything at this price.

On the list of best king mattress under $500, this mattress has the best edge support, I would say better than many above $500 as well. If you are a heavy-weight person or a couple this mattress won’t disappoint you.

Motion Isolation

Not too good, but still better than many mattresses in the price range, the bounce is quite good, and I would rate motion isolation to be above average.

User Experience and Reviews

I contacted users of this mattress who have been using it for years, there are a few things I would like to mention about the mattress that they have told:

  • some of those who bought this mattress once, have bought it again or have recommended this mattress to someone
  • there are a lot of users who stated they have experienced reduced back and neck pain
  • many users said the mattress to be the best king mattress under $500
  • The mattress is durable
  • The firmness is just perfect

“I have to admit, it has been fantastic and far better than the bed I had previously which ran about $1200 five years ago. I actually love it.”

“Shockingly it’s been fine ever since we received it. We haven’t had any issues and the cats haven’t been able to destroy it!”

“The firmness is perfect! Just slightly on the firm side, but it contours to your body still. If I rate it between 1- 10, 1 being soft, 10 being stiff as a board, I’d give it around – 6 to 6.5. I’ve had this mattress for 3 months now and it’s still great! I rotate it every 2-3 weeks when I wash my the sheets, pillow cases, etc. king story short, it’s the best mattress I’ve ever owned and I’m so glad I bought it. Buying it online made me nervous, but I’m so glad I went through with it!”

Who Should Buy the Siena Memory Foam Mattress

Unlike the Novilla Vitality Hybrid mattress, the Siena mattress is not for everyone.

  1. Sleeper Type
  2. Edge Support
  3. Motion Isolation
Sleeper Type

The first thing is the sleeper type, when I slept my night on this mattress, I can say without any doubt that the mattress is suitable for those who are back or stomach sleepers, I would rate the firmness 7 out of 10 on the firmness scale.

If you are a side sleeper or a combination sleeper you won’t like this mattress as it is a bit firm. A back sleeper would really enjoy this mattress whereas it will be a good option for stomach sleepers as well.

Edge Support

I would consider the edge support to be average, if you want good edge support in a mattress, you should buy a firmer hybrid mattress, but given this is a memory foam mattress, it is still good comparatively.

Motion Isolation

I consider this factor important as I sleep with my wife and I do not want anyone to disturb me while I sleep.

I spent almost a week on this mattress, the motion isolation is pretty good and solid. You won’t usually get good edge support and motion isolation for a memory foam mattress under this price.

Sleeper Type

Back and Stomach Sleeper

Firmness

Medium firm to Frim

7 out of 10

Edge Support

Average

Better than other memory foam mattresses at this price

Motion Isolation

Good

Who Should Not Buy the Siena Memory Foam Mattress

If you are a:

  • Side Sleeper
  • Extreme Hot Sleeper
  • Heavyweight (250+ lbs)

If you are a side sleeper or a combination sleeper like me, you can avoid this mattress and look for other options. The side sleeper should choose a softer mattress, the best would be to go for a hybrid mattress.

Apart from this, the cooling is not that great, it has memory foam without any cooling gel which won’t be good if you are an extremely hot sleeper.

The support of the mattress is good but not best, you may struggle a bit if you are a heavyweight person over 250+ lbs.

User Experience and Reviews

According to some of the users of this mattress:

  • The mattress is not soft, will be good for back and stomach sleeper
  • Given the price the mattress is quite comfortable
  • The quality is good and its durable
  • You may see some cost cuttings on the mattress, but you can;t expect much from a budget mattress

“We bought a Siena mattress 6 months ago and it’s pretty sweet. I sleep like an infant. After owning a Casper that cost 3x the price, I can tell you it’s the same exact thing.”

“We bought a Siena king-sized bed earlier this year. Honestly, it’s been pretty amazing. A little on the firm side (which I like) but if you’re used to soft, maybe not the best. Haven’t noticed any wear or change since I bought it back in March. It’s my primary bed and I’d say there is practically 0 difference from the Casper bed we used to have. As a guest room bed, I’d say your guests will be quite happy!”

Who Should Buy the Linenspa Memory Foam Hybrid Mattress

A good king-size mattress under $500 is really hard to find, but Linenspa memory foam hybrid mattress should surely be on your list for some reasons:

Sleeper Type

This mattress is best for back sleepers and side sleepers but may not be that great for stomach sleepers as your lower back may elevate high and not align with the shoulders.

I would rate the firmness of the mattress to be 6.5 out of 10 which is medium firm and should have been a good mattress for all sleeper types but it’s because of the type of springs making it a good choice for back and side sleepers.

Edge Support

If you are a heavyweight person you may not like the edge support of this mattress, however, a lightweight person may not feel the discomfort, I would consider the edge support to be average.

Motion Isolation

Motion isolation is average given the price, again, you can’t expect all the things and features in one mattress which is this cheap.

Sleeper Type

Back and Side Sleepers

Firmness

Medium Firm

6.5 out of 10

Edge Support

Not Good for Heavy Weight People

Who Should Not Buy the Linenspa Memory Foam Hybrid Mattress
