While people's may turn to Amazon this week for Prime Day mattress deals, plenty of popular bed-in-a-box brands are throwing their own rival sales. For instance, the Nectar Classic Memory Foam Mattress, now $552 (was $649) in a queen at Nectar, is now offering even more value for money.The Nectar Premier may appear in our best mattress guide for its side-sleeping, body-cradling comfort, but we think the Nectar Classic is the mid-range hero that outperforms its mid-market price tag. Testers felt it offered medium-firm support for all sleep positions, suiting back sleepers the most.This Nectar deal goes to show that the best Amazon Prime Day mattress deals aren't necessarily at Amazon. Here's why we think the Nectar Classic offers the best value for money and the advantages of buying it from Nectar over Amazon.The Nectar Classic offered medium-firm support

(Image credit: Future)The Nectar Classic is one of the best memory foam mattresses on the market thanks to its mid-range price and medium-firm support that offers that Goldilocks-level of comfort for all sleep positions. While it may not be as pressure-relieving as some of the best mattresses for side sleepers, it's ideal for back and combination sleep styles.Nectar mattress sales are pretty static, tending to boast the same mid-range prices every month. However, this $552-for-a-queen deal deviates from the normal $649 sale price.Another perk of buying from Nectar (besides this surprise Prime Day-rivalling deal) is the guaranteed benefits. Buying a mattress from Amazon means you're usually facing a murky return policy, but Nectar's benefits are all there in black and white: a 365-night sleep trial, free shipping and free returns, and a lifetime warranty.Smaller budget?
