Best Mattresses

(Image credit: Casper)

From our experience, the best mattress is one that’s supportive, comfortable, and reasonably priced. There are plenty of online mattresses to pick from, but some are leaps and bounds ahead of the others in terms of quality. Plenty of them make audacious claims about delivering your best night’s sleep, but precious few actually deliver on that promise. But we have the best here in our guide of the best mattresses you can buy online.

Purple Mattress

Adapts to your body for support and comfort

If you’re experiencing back or joint pain, rest easy on the Purple mattress. There’s no need to compromise between comfort and support, as it offers both across the range. 


  • Excellent for pressure relief and joint pain
  • Ideal for hot sleepers


  • Heavy to move around
  • The mattress can feel bouncy

The Purple mattress has a unique hyper-elastic polymer mattress top which they call Purple Grid technology. This grid adapts to your body to offer the comfort and support that you need and to help ease any aches and pains you may be experiencing. The Purple Grid technology also has over 2800 open-air channels which can help neutralize body heat so you don’t get too hot overnight which can often happen with memory foam mattresses.

Made up of three layers each designed to relieve pressure points and maintain support on body contours. The mattress composition starts with two-inches of purple grid technology which is then bolstered by two layers of polyurethane foam beneath. It has good edge-to-edge support thanks to the edges being reinforced with denser foam. While the mattress does have a little more bounce, the movement is absorbed by the thick foam core.

Best mattress for back sleepers

Casper Hybrid

No sagging after prolonged use

Enjoy the best of both worlds with this pressure-relieving spring and three-layer memory foam hybrid mattress from Casper. 


  • Enhanced edge support
  • Great for back and side sleepers
  • Provides pressure relief


  • Mattress may be too firm for some

For those who like memory foam but are not ready to give up on their springs just yet, the Casper Hybrid is the perfect solution. This mattress combines springs that relieve pressure on your joints and back while providing comfort and support, especially those who sleep on their backs. The Casper Hybrid mattress is made up of four-layers with three foam layers on top of a layer of 7-inch pocket springs. The edge to edge support is superb and a lot firmer than many of the rival hybrid beds meaning it’s a comfortable bed if you like to sleep on the edge or you struggle to get in and out of your bed. 

The firmness rate is around 8, so it is better suited to customers who like a firm mattress but because of the springs, it does have a certain bounce that may appeal to those who like a medium-firm mattress. And while the Casper mattress offers excellent relief for aching joints and back pain, it is less comfortable for front sleepers.

Best mattress for side sleepers

Leesa Mattress

For dominant side sleepers

The Leesa mattress is ideal for side-sleepers with its light, pressure-relieving foam, and good temperature regulation. 


  • Soft to sleep on
  • Excellent for side sleepers


  • Can’t be used with a box spring base
  • Not suitable for heavy sleepers

This foam mattress is composed of Avena foam, memory foam, and base foam, making the Leesa one of the softer-feeling mattresses we tested, which is perfect for those who tend to sleep on their side. The top layer is designed to be breathable so the bed doesn’t get too hot which is common with all-foam mattresses. The Leesa is also extremely good for motion isolation as the foam means you won’t feel your partner fidgeting or getting up. 

The mattress does have a gassy smell that you can smell even through the plastic. It does become less prominent as time goes by. The Leesa isn’t designed to be used with a box spring base. Also, several users have pointed out that the Lessa mattress is not supportive enough for larger sleepers.

Best cooling mattress

Brooklyn Signature

Savor sweet, cooling relief

The Brooklyn Signature Mattress isn't bouncy, supportive, and great for couples, especially if one is a fidgeter or gets hot overnight. 


  • Perfect for any type of sleeper
  • Cooling design


  • Not a bouncy mattress

The Brooklyn Signature is hands down the best cooling mattress thanks to the top layer of the mattress being infused with TitaniumGel and the additional airflow created via the pocketed coil layer. This helps the entire mattress maintain a comfortable temperature no matter what the weather. It’s also a great mattress for any type of sleeper and perfect for those who love the feel of memory foam but need the support of a sprung mattress. 

The Brooklyn Signature Hybrid is made up of four layers of foam and pocketed coils. This mattress is ideal for those who share a bed for two reasons; the motion isolation is fantastic - especially for a bed with coils. Secondly, the edge support is strong, so you can have distance without the worry of falling off.

Nectar Mattress

Excellent temperature regulation

When it comes to combining great support with top-class temperature regulation, the Nectar Mattress is a rarity: a memory foam mattress that's cool and firmly supportive. 


  • Comfortable and supportive
  • 365-night trial


  • Some may find it too firm

Nectar is one of the best value mattresses on the market. It comes in twin, twin XL, full, queen, king and cal king sizes. And while it is priced lower than most other mattresses it doesn’t compromise on comfort. It offers a medium-firm comfort and is constructed of five layers starting with a cooling cover that promotes air circulation and is bed bug resistant. The next layer is a quilted gel memory foam which will contour your body, then you have a gel memory foam layer which will help distribute weight evenly and provide pressure relief. Followed by two layers of hi-density memory foam to support the body and provide a stable foundation. 

The other thing that we really love about this mattress is that it can hold up to a combined weight of 800lbs. So if you’re a heavy sleeper, it won’t sag or dip too much and still provide adequate pressure relief. This mattress also comes with a whopping 365-night trial period and should you not fall in love with this mattress within the first year, they’ll collect it and issue a full refund, no questions asked. 

How to choose the best mattress for you 

Factors such as whether you sleep on your side, back or stomach, whether you share a bed with a partner and even your weight and height should be things you consider before you make your next mattress purchase. 

Firmness is another thing that you should factor in, usually a firmer mattress suits heavier sleepers or those who sleep on their front or back. Medium firmness is suited to those who need extra support for their spine, back, and neck. While those who are side sleepers benefit from a softer mattress that will mold to your body’s natural curvature. 

If you share a bed then you’ll want to opt for a mattress that has limited motion transfer. Not everyone sleeps the same so if you’re sharing with a partner who gets up and down a lot, or tosses and turns, the last thing you want is a spring mattress as they can be bad for motion transfer, while memory foam mattresses are great at limiting movement.
