Made by the same parent company, Resident Home, there are, as you’d imagine, quite a few similarities between the Nectar Classic and the Siena Memory Foam mattress. But although both are affordable all-foam mattresses, there are enough differences to make a Nectar Classic vs Siena Memory Foam mattress head-to-head an intriguing battle.
The Nectar and Siena are two of the best mattresses we’ve tested this year, and we think they’re two of the best memory foam mattresses you can buy. However, they're both suited to differing sleep styles and in this guide we’ll compare the two closely to help you decide which is best for your needs.
In the Presidents’ Day mattress sales there are some great bargains to be had, including big savings from Nectar and Siena. This could be the perfect time to invest in a new mattress, so let’s take a closer look under the covers to see which mattress you should choose…
Nectar Classic vs Siena Memory Foam Mattress: Price & Trial
- Both brands offer evergreen deals, so you’ll never pay full MSRP
- The Nectar Classic has a 365-night trial and lifetime warranty
- The Siena Memory Foam has a 180-night trial and 10-year warranty
Regular mattress sales at both Nectar and Siena ensure you’ll never pay full MSRP for either mattress, and they're both affordable choices. However, if you are on a tight budget, the Siena is the cheaper option. For a long time the evergreen Siena mattress sale reduced a queen size to $399 (was $769) but in recent weeks it's been knocked down to the incredible budget price of $359. This is the best cheap mattress our experienced sleep team has tested.
A year-round Nectar mattress sale means you’ll never pay full MSRP for the Nectar Classic, either. Prices start at $349 for a twin (MSRP $1,081) and a queen is regularly sold for only $649 (MSRP $1,664). We rarely see a bigger saving than this, but for Presidents' Day, Nectar has upped the deal by adding a free bedding bundle with every mattress purchase. Worth up to $898, the bundle includes pillows, a mattress protector and sheets.
Extras wise, the Nectar blows the Siena out of the water with a 365-night sleep trial and a lifetime warranty. The Siena comes with only a 180-night trial and 10-year warranty but considering how cheap the Siena is, we think the benefits are still generous.
Nectar Classic vs Siena Memory Foam Mattress: Materials & Design
- Both mattresses have an all-foam design
- The Nectar Classic is 12” high and has three interior foam layers
- The Siena Memory Foam is 10” high with two layers of foam
The Nectar and Siena mattresses are both available as hybrid builds, but in this guide, we're focusing on the all-foam models. Both mattresses have relatively simple designs, so let's take a look at their similarities and differences.
Nectar’s top cover is woven with cooling fibers, with an antimicrobial treatment applied for a healthy sleep surface. Up next is a one-inch layer of pressure-relieving memory foam, backed up by three inches of responsive support foam to promote spinal alignment. The base of the mattress is an eight-inch layer of foundation foam, providing support. It's finished with a durable shift-resistant fabric cover that stops any layers from shifting.
The Siena’s design is a little simpler. Starting at the top, you’ll find a soft, breathable polyester cover, followed by a layer of responsive gel-infused memory foam. Underneath this is a base layer of support foam, while a shift-resistant lower cover keeps everything in place.
Both mattresses feature in our best mattress in a box guide and will arrive at your house vacuum packed and rolled into a box. It’s worth noting that there’s quite a difference in weight between the two – a queen size Nectar weighs 83lbs, whereas the same size Siena is 68lbs. This will make setting up the Nectar slightly more difficult, but once on your bed frame, the weight is unlikely to make a difference.
Nectar Classic vs Siena Memory Foam Mattress: Comfort & Support
- Nectar Classic is a medium firm mattress, rated 7.5/10 by our testers
- We rated the Siena as firm (9/10) (it's rated 6.5 by Siena)
- Both mattresses have excellent motion isolation
In our Nectar Classic Memory Foam mattress review, our testers rated the bed a 7.5 out of 10 on the mattress firmness scale. That's a medium-firm feel, and slightly firmer than the official Nectar rating of 6.5/10.
That’s not to say that there isn’t plenty of contouring from the top layers, and the ample pressure relief makes this one of the best mattresses for side sleepers you can buy. Most of our side sleepers loved the feel of the mattress, but it could be a little firm for lightweight side sleepers (consider the softer Zinus Green Tea Memory Foam Mattress instead.)
The dense foams in the Nectar also mean the mattress is supportive enough for back sleepers, who should feel that their spines are kept aligned and hips lifted. However, most stomach sleepers will need something firmer. Which brings us to...
Siena rate its mattress at 6.5/10 but in our Siena Memory Foam mattress review, our testers unanimously felt that it slept far firmer, rating it at 9/10. This firmer support means it’s one of the best mattresses for stomach sleepers, with subtle body contouring keeping these sleepers’ hips raised and spines aligned. The sturdy support across the back could suit some back sleepers as well, but side sleepers will likely find it too firm.
Edge support on the Siena is particularly impressive, which is surprising for an all-foam mattress in a box as these beds can sometimes be a bit lackluster in this department. And indeed, the Nectar’s edge support is okay, but not great. With springs and foams, the best hybrid mattresses tend to provide superior edge support to all-foam designs.
As you’d expect from all-foam mattresses, motion isolation on both the Nectar and the Siena is excellent. The thick cushioning of both models absorbs movement to prevent it from traveling across the bed, so you won't wake up every time your partner shifts.
Nectar Classic vs Siena Memory Foam Mattress: Temperature Control
- Both mattresses offered good temperature regulation
- Both maintain a neutral feel but aren't cool to the touch
- Hot sleepers should consider a specialist cooling mattress
Budget all-foam mattresses are notorious for trapping heat, which can cause sleepers to wake up uncomfortably warm. So, we were pleasantly surprised with the temperature control of both the Nectar and the Siena during testing. Both mattresses scored 4/5 from our review teams, and while they weren't actively cooling, they stayed a neutral temperature.
The Nectar uses a cover infused with cooling fibers to draw heat away from the body and the 365-night trial allows you to test the bed in every season. The Siena also has a breathable cover, while the firmer feel helps air circulate (less 'hug' to trap warmth.) However, very hot sleepers should consider the best cooling mattresses, which use specialist designs to eliminate heat build-up.
Nectar Classic vs Siena Memory Foam Mattress: Which should you buy?
Buy the Nectar Classic Memory Foam Mattress if...
✅ You’re a side sleeper: With a slightly softer sleep feel, the Nectar Classic does an excellent job of contouring around the pressure points of the shoulders and hips to soothe side sleepers..
✅ You share your bed with a restless sleeper: One of the most impressive things about the Nectar Classic is how well it isolates motion. And the fact it’s suited to a wide range of sleepers means it will be easier for you and your partner to get comfortable.
✅ You want a long trial period: The year long trial offered with the Nectar Classic gives you a huge amount of time to see if the mattress is suited to you. Plus, you can test it in every season to see if it's cozy enough for winter and cool enough for summer.
Buy the Siena Memory Foam Mattress if…
✅ You’re a stomach sleeper: With a firmness rating of 9/10, the Siena offers plenty of support for stomach sleepers, ensuring that their hips don’t drop too far into the mattress.
✅ You’re on a tight budget: There aren’t many mattresses this cheap that still offer good quality and a comfortable night’s sleep. The Siena is an absolute bargain.
✅You’re a hotter sleeper: It’s not a cooling mattress per say, but we were highly impressed with the Siena’s ability to keep our testers cool, even during a sweltering August.
