Need Some Help Narrowing Down Your Options? Here's Some Additional Information to Consider:
Picking Your Mattress Type
Gel Memory Foam Mattresses

If you're thinking about getting a gel memory foam mattress, this king-size hypoallergenic mattress could be a good choice. These breathable mattresses allow air to circulate freely, keeping them ventilated to extend their lifespan. With even weight distribution, they prevent sinking from occurring. They are made of various materials, giving you a range of foam densities to choose from. Providing pressure-point relief, they will reduce any soreness in your joints. Due to superior motion isolation, these mattresses are great for couples with a restless sleeper.

Hybrid Mattresses

If you're thinking about getting a hybrid mattress, this king-size hypoallergenic mattress might be a good choice for you. These hybrid mattresses offer pressure point relief, helping to reduce tension in your joints, so you will wake up feeling energized and ready to go. Designed to dissipate heat instead of absorb it, they will enhance sleep quality by keeping a comfortable body temperature. With even weight distribution, they are less likely to droop with extended use. Featuring a range of foams, they provide just the right amount of cushion you desire. They are built with various coil types to offer firm to plush support for more give. One downside is that hybrid mattresses are expensive, so if you're on a budget, this might not be the best choice for you.

Memory Foam Mattresses

If you're thinking about getting a memory foam mattress, this king-size hypoallergenic mattress could be a good choice. Providing pressure-point relief, these mattresses will reduce any soreness in your joints. Featuring a range of foams, they provide just the right amount of cushion you desire. Due to superior motion isolation, these mattresses are great for couples with a restless sleeper. One downside is that they aren't waterproof, so you'll want to be extra careful and make sure that they don't come into contact with moisture. Moreover, these memory foam mattresses can smell a bit like chemicals at first, sometimes lasting up to a couple of weeks before wearing off.

Let's Go Over Mattress Comfort
Firm Mattresses

With only one king-size hypoallergenic mattress out there with a firm feel, you'll want to jump on the opportunity and check it out if you think it might be what you need. Firm mattresses offer proper weight distribution, adequately supporting your back and joints and other sensitive areas. They are perfect for people who find it more comfortable to sleep on their back and have an indentation load deflection ranking of 34-36 pounds. Improving circulation and blood flow, they promote deeper sleep. One downside is that these mattresses might be uncomfortable if you're not accustomed to sleeping on hard surfaces, so it can take a few days to get used to them. In addition, they can put painful tension on specific pressure points, so if you want a mattress that relieves pain in pressure points, this is not the mattress for you. If you feel like a firm mattress is right for you, you'll want to check out a king-size hypoallergenic mattress.

Ultra Plush Mattresses

If you're having trouble deciding on an ultra plush mattress, a king-size hypoallergenic mattress could be a good choice for you. These mattresses are built with an indentation load deflection rating of 14-19 pounds and are ideal for individuals who sleep on their sides. These contouring support mattresses adjust to your body for enhanced comfort. They provide extra support, helping to alleviate any back problems or joint pain that you're experiencing. However, they may be problematic if different sleepers will be using the bed, causing the surface to sink if there is a drastic difference in weight. Moreover, the surface will become softer with time, so they'll wear down faster than other types of mattresses and you'll probably want to replace them sooner.

Luxury Firm Mattresses

If you're considering a luxury firm mattress, a king-size hypoallergenic mattress could be a good choice for you. Luxury firm mattresses offer proper weight distribution, adequately supporting your back and joints as well as other vulnerable areas. They are perfect for people who find it more comfortable to move from their back to sides when sleeping and have a 29-31 pound indentation load deflection ranking. They are a win-win situation, catering to couples that have one person who prefers to sleep on their side and the other on their back or stomach. Something to consider is that they are less durable than memory foam mattresses, lasting between 7-10 years at most. On top of that, they provide less support than other mattresses, so you might want to search for a firmer mattress if you have back discomfort.
